What effect does increase salinity have on the density of water? 1. No affect unless temperature also changes

2. Decreases density

3. Increases density

3

Explanation:

For example,The density of seawater depends on the content of salt. It is known that the density of salt is 2.165g/cm3, so the more salt, the greater the density of mixed liquid.

If you know that dissolution of salt only marginally affects the volume of the solution, how would you expect the density to evolve? It should reasonably increase.

Explanation:

at a given temperature, Should salts be dissolved in the water, and the volume remains reasonably constant, the density

. A solute binds water molecules around itself in a coordination sphere, and should a salt be dissolved, both anion and cation must be solvated; hence an increase in solution density with respect to water.
