Explanation:
Decrease in H30+ ions concentration per unit volume results in formation of dilute acids.
• It is a highly exothermic reaction.
Acids when dissolved in water release large amount of heat. If water is added to concentrated acid then the heat generated may cause the mixture to splash out and cause bums. Hence to avoid burns acid must be added drop wise into water with constant stirring. So that the heat generated spreads over in water.
