An acid-base reaction will always produce water and which one of the

following?

A. Flames

B. Acid

C. Color

D. Salt

Answer: Option D) Salt

Explanation:

An example of acid-base reaction is

HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l)

Acid + base → Salt + Water.

Here, water H2O and salt, NaCl are produced.

Usually, the acid, aqeous HCl reacts completely with an appropriate amount of the base, aqueous NaOH to produce salt, aqueous NaCl and water, liquid H2O only, in a process also known as neutralization reaction
