These electrostatic effect give rise to a shrinkage of the water. We will list a couple of things that will lead you to the most important things regarding this topic. Here, we will try to give you some guidance in order to find the answers and understand the matter. But, what can be said about this density change. The colder and saltier the ocean water, the denser it is. Cold water is denser than warm water, and salty water is denser than fresh water.

Both temperature and saltiness (salinity) affect the density of water. Density is an object’s mass (how much matter it has) per unit of volume (how much space it takes up). For which pair of functions is the exponential consistently growing at a faster rate than the quadratic over the interval mc015-1. The density of the NaCl solution is 1.0 g solution/mL solution. In this way the field tends to disrupt hydrogen bonded structures in liquid water, and to compress the water molecules surrounding an ion. This phenomenon, as we can see, is caused by the change in the density of the water. Water density is affected by the temperature, salinity (saltiness), and depth of the water. Differences in density drive slow-moving ocean currents in the deep ocean. The property of ocean water that affects climate the most is its heat capacity.Option (C). The interaction of the electrostatic field of an ion with water tends to align the dipolar water molecules in the direction of the field. See this excerpt from a study on the volumetric effects due to ion-solvent interaction in aqueous electrolyte solutions: In this more ordered arrangement, the ions effectively fill the voids between the water molecules, and the volume of the water only increases slightly. The positive Hydrogen ends of the water molecules are attracted to the negatively charged Cl ions, and the positive oxygen ends are attracted to the positively charged Na ions. The Dead Sea, for example, has a high saline level (31) and its density is 1.24kg/L. Because of the geometry of water molecules, they are essentially dipoles with “positive and a negative ends”. As you increase the salinity of water, the density of the salt adds to the waters density. Interestingly, the dissolved salt does not increase the volume of the water by the volume of the added salt, and this is due to the charge of the Na and Cl ions and the H 2O molecules.

When salt (sodium chloride or NaCl) dissolves in water, there is a significant increase in mass of the solution due to the relatively higher molecular mass of the dissolved ions Na (22 g/mol) and Cl (35.5g/mol) when compared to water or H 2O (20 g/mol).
