Which is the safe method for mixing acid with water?

Answer and explanation

Correct answer: Add acid slowly into water

Dilution of a concentrated acid with water is usually exothermic, meaning that considerable heat is released. If water is poured into a small amount of concentrated acid, the water may heat suddenly, boil, and eject corrosive acid droplets. The safe laboratory rule is to add acid slowly to a larger volume of water while stirring and using protection. Therefore option B is correct; the other methods increase splash, pressure, or heating hazards.
