wlad13 [49]

Answer:

The correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

Explanation:

Diluted acids are more corrosive then undiluted due to the presence of more H+ ions than the undiluted acids. The More the H+ ions are added the more corrosive the acid is.

When water is mixed with strong acid the hydrogen ions reacts with acid ions and a exothermic reaction takes place that release high amount of energy which boils violently, to avoid any accident it is advised to lab workers to wipe  if any splash self before washing.

Thus, the correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.
