For pure water, density increases as the temperature decreases. Many properties of seawater, such as density,. Water is classified into Freshwater, Brackish water, saline water, Brine are the types. The average usually is reported as 1.027 kg/L at 25 degrees-C. Density calculated for salinity S = 35000 mg/l. For instance, although seawater contains about 2.8 times more bicarbonate than river water, the percentage of bicarbonate in seawater as a ratio of all dissolved ions is far lower than in river water. Chemical reactions that take place in seawater can be attributed to the solvent properties of water, ion- water and ion-ion interactions. However, when we collect small samples of ocean water break down the chemical formula into its elemental properties, we can see that seawater is as follows: Oxygen - 86% Hydrogen - 11% Chloride (Cl) - 2% Magnesium (MG 2) - 1% Sodium (NA) - 1% Calcium (CA 2) - 0.04% Sulfur - 0.1% Potassium (K) - 0.04% Carbon - 0.003% Bromine - 0.007% Download "Water as a resource" pdf file. 2. View Chemical Oceanography - Properties of Seawater - Essential Questions - Virtual.pdf from SOCIAL STUDI 101 at Stonewall Jackson High School. What is a chemical property of seawater? Water, Water, Everywhere Over 70% of our world is covered by water, but this water is salt water! Water is a colourless and tasteless liquid. Seawater temperature, saturation pressure, specific volume, specific heat, electrical conductivity and absolute viscosity. Pure water, like distilled water, has a pH of 7 (neuter). Water is a universal solvent. Salinity is normally quoted in units (parts per . Understand what make the oceans salty and where the salts come from I. Water can dissolve ions present in soils and rocks. Temperature, salinity and density. The molecules of water have extensive hydrogen bonds resulting in unusual properties in the condensed form. Seawater also contains various dissolved atmospheric gases, chiefly nitrogen, oxygen, argon, and carbon dioxide. Chemical properties of seawater. Become familiar with the basic chemical and physical properties of seawater 2. The most obvious property of seawater is its high salinity. Seawater density and salinity increases with decreasing temperature and with depth where the highest densities are the result of pressure. Occurs in three states. Compared to the other atmospheric gases, the amount of carbon dioxide dissolved in saturated seawater is unusually large. They are given as functions of temperature, pressure, and salinity. Approximately 3.5 percent of seawater is composed of dissolved compounds, while the other 96.5 percent is pure water. 3. This chapter presents the definitions of the principal physical properties of the seawater, including pressure, temperature, salinity , density, density anomaly, specific heat, and thermal. . Molarity = moles per litre of solution = M The basic properties of seawater and their distribution, the interchange of properties between sea and atmosphere or land, the transmission of energy within the sea, and the geochemical laws which are governing the composition of seawater and marine sediments, are the fundamental aspects studied in the subject oceanography. Water has its own physical, chemical and biological properties. The physical and chemical properties of seawater vary according to latitude, depth, nearness to land, and input of fresh water. The temperature and salinity ranges are 0 - 120 C . ionic bonds are broken What is the most common ion in the ocean? The density (specific gravity) of seawater ranges from 1.020 to 1.030 kg per liter (or grams per cubic centimeter). The electrical conductivity of seawater ranges from 44,000 to 58,000 mhos/cm (or S/cm) with an average of about 50,000 mhos/cm. Freezing temperature of seawater is 1.9oC at a salinity of 35 parts per thousand. This also leads to high melting and boiling points. Bicarbonate ions constitute 48% of river water solutes but only 0.14% for seawater. Chemical properties of water. Chemical and physical properties of seawater The six most abundant ions of seawater are chloride (Cl) sodium (Na+) sulfate (SO24) magnesium (Mg2+) calcium (Ca2+) and potassium (K+). The properties given by these codes are those needed for design of thermal and membrane desalination processes. By weight these ions make up about 99 percent of all sea salts. CO2 Dissolved CO2 concentration is high near the ocean bottom due to decay What happens when a salt is dissolved in the water? Water (or H 2 0) is a molecule composed of one oxygen atom and two hydrogen atoms attached together with a chemical bond (energy that holds atoms together). Most fresh water has a pH between 6 and 8, apart from acid rains, of course, whose pH is below 7. Seawater has the ions containment which consist of some major ion substances as mentioned above. What are the three basic physical properties of seawater? However, most of ocean has the salinity level of 35%. Seawater is made up mainly of liquid water (about 96.5 percent by weight) in which chloride (Cl) and sodium (Na) are the dominant dissolved chemicals. This page provides tables and a library of computational routines for the thermophysical properties of seawater. This research investigated physical (temperature, salinity, and density) and chemical (dissolved oxygen, ammonium, nitrate, nitrite, phosphate, and silicate) properties of offshore seawater in the Red Sea northern Gulf of Aqaba; Jordanian Site were measured during 2013-2015 to assess the temporal and seasonal variation of the upper 400 m of the water column. The salt makes the water heavier which means it can support heavier objects more than a lighter liquid can , causing it to float . What are some ways that we can take the salt out or desalinate the sea water to provide plentiful freshwater? Name_ Class/Section_ DUE Date_ Chemical Oceanography - The physical properties of seawater-temperature, salinity, pressure, density, and related quantities such as potential density, heat capacity, sound speed, and others-are of fundamental importance to physical oceanography. Temperature influences density. Water quality Water quality is an important aspect on the earth. Seawater properties like density, saturation pressure, specific heat, electrical conductivity and absolute viscosity. 30 degrees Dissolved CO2 concentration is low near the ocean surface due to _____ photosynthesis What is the main factor that controls the pH of seawater? As compared to other liquids, water has a higher specific heat, thermal conductivity, surface tension, dipole . The physical and chemical seawater data results collected in front of the Marine Science Station during the year 2006 are shown on Table 3.7). In short, seawater has some basic chemical properties based on its containment. Some of the important atmospheric gases found in seawater include: nitrogen, oxygen, carbon dioxide (in the form of bicarbonate HCO 3 ), argon, helium, and neon. Table 3.7 Monthly averages of measured physical and chemical offshore water parameters for the year 2006 in front of the MSS (ADC 2008 ) A toms a. fundamental particles of matter defining the elements b. cannot be broken down into smaller particles using conventional chemical procedures c. examples of some of the major elements comprising living things. Uploaded on Nov 16, 2012. The remaining 0.73% comprises trace amounts of bromide, borate, bicarbonate, strontium, and fluoride. Seawater is essentially alkaline, having a pH of around 8. What is water? Prof. A.Balasubramanian Salinity influences this relationship in that the saltier the water, the denser it becomes. Some other components of seawater are dissolved organic substances, such as carbohydrates and amino acids, and organic-rich particulates. 803 Views Download Presentation. Physical properties of water. How are the properties of seawater interrelated? The common table salt you use to flavor your food is composed of precisely the same elements. 1. Chemical properties of seawater. OCN 623 - Chemical Oceanography Salt dissolved in ocean water alters the properties of water Freezing point of seawater is ~ -1.8C Density continually increases to freezing point Drives the circulation mode of the oceans -completely different from freshwater in lakes Molar units 1.
