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 ?
(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.
Explain the action of dilute hydrochloric acid on the following with chemical equation crushed egg sheels.
•HCl + CaCo3 --CaCl2 + H2O + Co2
When hydrochloric acid reacts with crushed egg shells and utilise to formation of calcium chloride carbon dioxide and water.
