Does salt water have a pH?

Answer 1

"Does Salt Change the pH of Water?

• It depends upon the pH of the water into which the salt is being introduced. Chemically speaking, salt is a basecompound, falling smack in the center of the acid-alkaline spectrum (at 7). If introduced to water which has a high pH, the pH might be lowered incrementally toward the center of the pH spectrum depending on how much water there was and how much salt was introduced. If the water had a very low pH, making it very acidic, the salt would increase the pH toward the center of the spectrum."

Answer 2

Salt water is neutral in nature and usually has a pH of 7.0.

But this is the case only when salt is formed by the reaction of strong acid and strong base.

When a salt is formed by the reaction of a strong acid and weak base, then the salt formed is acidic and has a pH < 7.

When a salt is formed by the reaction of a strong base and weak acid, then the salt formed is basic in nature and has a pH > 7.

Answer 3

Yes, salt water does have a pH value. The pH of salt water will generally depend on the amount of dissolved salts present in the water, but it is usually slightly basic with a pH around 7.5-8.4.

Answer 4

salt makes a liquid's pH near neutral (around 7)

Answer 5

For example sodium bicarbonate.
