When handling acids, which statement is true regarding the correct procedure?

The statement that is true regarding the correct procedure for handling acids is that you should always pour acid into water. This method is crucial because when concentrated acid is added to water, it disperses rapidly and the heat generated is absorbed by the larger volume of water, which helps to prevent the risk of splattering or boiling.

In contrast, if water is poured into acid, it can cause a violent exothermic reaction. The concentrated acid can cause the water to boil rapidly, leading to dangerous splashes of acid, which can result in serious injury. This fundamental approach is paramount in ensuring safety when working with corrosive materials, particularly strong acids.

Understanding this principle is essential for anyone involved in chemical handling or laboratory work, as it underpins important safety protocols and practices designed to minimize risk and protect individuals from chemical hazards.
