Question

which addition would not change the ph of 10ml of dilute hydrochloric acid

Answer 1

I think it might be water

Answer 2

Answer:

Buffer solution is formed so the ph would not change.

Explanation:

• A buffer solution (also known as a pH buffer or a hydrogen ion buffer) is an aqueous solution that contains a weak acid and its conjugate base, or vice versa.
• When a modest amount of strong acid or base is added to it, the pH of the solution does not vary much.
• A buffer composed of acetic acid and sodium acetate CH3COOH + CH3COONa is an example of a weak acid and its salt.
