Question

What effect does increase salinity have on the density of water?

1. No affect unless temperature also changes

2. Decreases density

3. Increases density

Answer 1

Answer: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.

Step-by-step 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.

Answer 2

3

Step-by-step 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.
