15ml of water and 10ml of sulphuric acid are to be mixed ina beaker

(a) State the method that should be follwed with reason

(b) What is this process called ?

\huge\blue\bigstar\purple{ANSWER}

(a) The method to be followed is that , acid (sulphuric acid) should be added to water , and not vice versa. That is , water should NEVER be added to acid. This is because water reacts very vigorously when added to acid, and releases a large amount of heat , and splashes the concentrated acid( sulphuric acid) out of the container. Hence, it is COMPULSORY to add acid to water , as only a little amount of heat is released,and also the reaction won't be that violent.

(b) The process of adding acid to water , is called dilution of acids.
