Flashcards

What is an acidic salt?

A salt that forms an acidic solution when dissolved in water.

What is salt hydrolysis?

Hydrolysis occurs when a salt reacts with water to produce an acidic or basic solution.

What is a salt and what factors determine its properties?

A salt is formed by the reaction of an acid and a base, and its properties depend on the strength of the acid and base.

What is a salt that does not undergo hydrolysis?

A salt that does not undergo hydrolysis will not change the pH of the solution when it is dissolved in water.
