Why should acid be added slowly to water while mixing acid with water?
Answer and explanation
Correct answer: Because the process releases heat and may cause splashing
Diluting a concentrated acid with water is generally exothermic, meaning that heat is released. If water is poured rapidly into a small amount of concentrated acid, the water can heat suddenly and boil locally, causing dangerous acid droplets to splash. Therefore acid should be added slowly to a larger volume of water with stirring and protection. Option A is correct.
