What is the safe method while diluting an acid?
Answer and explanation
Correct answer: Add acid slowly to water
Dilution of a concentrated acid with water is exothermic, meaning that considerable heat may be released. The safe laboratory procedure is to add the acid slowly to a larger volume of water while stirring, allowing the heat to spread through the water. Adding water directly to concentrated acid can make the small amount of water boil suddenly and splash corrosive acid. Thus, option A is correct.
