If a student first takes acid in a beaker and then adds water while diluting acid, what is the main mistake?

Answer and explanation

Correct answer: Adding water to acid can cause violent splashing

Diluting a concentrated acid is exothermic: heat is released when acid mixes with water. If a small amount of water is poured into a larger amount of concentrated acid, that water can heat suddenly, boil locally, and eject acid droplets. The safe laboratory rule is to add acid slowly to a larger volume of water while stirring and wearing protection. Therefore option A identifies the mistake and its hazard.
