There is a general rule in chemistry as to how salts affect solution pH.
If the salt of a strong base and weak acid is dissolved in water it will form an alkaline solution, whereas, the salt of a weak base and strong acid will form an acidic solution.
The salts of a strong acid and strong base or a weak acid and weak base will both form a neutral or near neutral solution.
For example,sodium sulfate will form a neutral solution when dissolved in water because it is the salt of a strong base and strong acid, whereas, tri-sodium phosphate will form an alkaline solution because it is the salt of a strong base and weak acid.
Sodium chloride is table salt and when it is added to water it breaks down into ions of sodium and chloride.
Neither of them reacts to water so adding it to water will only change the volume, not the pH.
In order for a type of salt to affect the pH it has to react with water to release or bind the hydrogen atoms from the water.

A triple-effect evaporator is a process that removes pure water from a salt water feed. The process consists of three units connected in series. The feed to the process contains 3.43 wt % NaCl in water. In the first effect, sufficient water is evaporated to concentrate the solution to 3.89 wt % NaCl. The second effect concentrates the solution further to 4.22 wt %, and the brine discharged from the process contains 5.02 wt % NaCl. a. Draw a diagram...
