Question

Concentrated H2SO4 is diluted by adding drop by drop : (a) Water to acid with constant stirring (b) Acid to water with constant stirring (c) Water to acid followed by a base (d) Base to acid followed by cold water

please help me as fast as possible​

Answer 1

(b) Acid to water with constant stirring

Explanation:

• Concentrated H₂SO₄ is diluted by adding drop by drop water to it with constant stirring.
• On dilution activity of acid increases.

Answer 2

Answer:

The right method to make concentrated acid dilute is to mix acid in water. If we mix water in concentrated acid, it may cause an explosion as the reaction is exothermic.

So, for preparing dilute solution of H
