Expert Answer:

Both the reactions are same, only thing is that dissolution of an acid or base in water is a highly exothermic reaction.
If water is added to the concentrated acid to dilute it, then a large amount of heat is generated.
This heat changes some of the water to steam, which can splash some acid on us and cause acid burns.
Sometimes, even the glass container may break due to the excessive heat.
This can also harm us.
Hence, acids like sulphuric acid or nitric acid should always be added to water with constant stirring.
