Explanation:

Dear student

Please find the solution to the asked query:

When an acid or base is added to water, an exothermic reaction takes place, which releases heat. This makes the beaker warm.

It is always advisable to add acid to water than water to acid. This is because the reaction between acid and water produces a lot of heat. So when water is added to acid, it results in vigorous boiling of the solution and the amount of heat produced is so large that it splashes the acid out of the container, which can result in acid burns. On the other hand, when we add acid to water, it is like adding a concentrated solution to water in small amounts. So comparatively lesser amount of heat is released.

Question :-

What happens when an acid or a base is added to the water. why does the beaker appear warm. why should we always add acid or base to the water and not water to the acid or base​

Answer:-

1.An acid or a base is added to water , the beaker becomes warm due to the reaction of Acid/base with water.

2.On adding,local temperature increases and the beaker becomes warm.

3.We should always add acid or base to water not water to acid or base , because while adding water to respective acid or a base , the local temperature increases rapidly and the beaker will be burst and the content will be spilled on us and the surroundings.

4.So we are adviced to add acid/base to water , and also while adding ,we have to continuously stir slowly.(Dilutation)

• Acid/Base + water —> Salt + hydrogen
