Question

why didnt you just clean the spill with water?
a) the acid reacts with water
b) the acid freezes the water
c) it could ignite
d) it would pollute the water

Explanation:

Strong acids (like concentrated sulfuric acid) react vigorously and exothermically with water, which can cause splashing of the corrosive acid, increasing safety hazards. The other options are incorrect: acids do not freeze water, acid-water mixtures do not ignite in this context, and pollution is not the primary immediate safety reason for avoiding water on an acid spill.

Answer:

a) The acid reacts with water
