Because it is safer: when you add a bit of water to a full container of acid, the acid can react violently and explode in your face. If you add a little bit of acid to water, the reaction would be tiny in comparison, so you have time to react if something goes wrong.
is soluble in water and will fizz when hydrochloric acid is added
sulphuric acid
it is gay

Mixing of acid with water is highly exothermic. Hence acid is added to water.Also, adding acid to water, if the mixture accidentally splashes you will be less likely to be injured by the dilute acid mix. Adding water to acid, if the mixture accidentally splashed you will be more likely to be injured by the still concentrated acid mix.
is Ca(OH)2 is soluble in water and will hissing when hydrochloric acid is added
Oleic acid is not miscible with water.
decrease.
HI, Hydrogen iodide, is an ionic compound which will dissociate when added to water. It forms a strong acid, hydroiodic acid.
When an acid is added to water it produces hydronium ion along with acid radical.
Water is composed of hydrogen and oxygen so naturally, no acid is involved. Unless if you intentionally added acid on water then that is another story
The equation when hydrochloric acid (HCl) is added to water (H2O) is: HCl + H2O → H3O+ + Cl-
