The dissociation of acid in water releases large amounts of energy in the form of heat. Because this energy cannot disperse easily through acid, it makes the material around it boil; this is a serious danger that can be avoided quite simply by adding acid to water, where the energy required to boil the solution is a lot higher and the heat can disperse more rapidly.
The compound produced when chlorine is added to water is hydrochloric acid (HCl). This reaction forms a mixture of hydrochloric acid and hypochlorous acid, which can help disinfect the water by killing bacteria and other harmful microorganisms.
When chlorine is added to water, it can react to form hypochlorous acid (HOCl) and hydrochloric acid (HCl). Hypochlorous acid is the primary disinfectant that helps kill bacteria and other pathogens in water, while hydrochloric acid can contribute to lower the pH of the water.
The pH of water will decrease when hydrochloric acid, a strong acid, is added to it. This is because the strong acid will increase the concentration of hydrogen ions in the water, leading to a lower pH.
When added to water, hydrogen (H+) ions produce acid. When hydrogen gas dissolves in water, it forms hydronium ions (H3O+), which lower the pH of the solution and make it acidic.
It is important to add acid to water instead of the other way around because adding water to acid can cause a violent reaction, leading to splashing and potential burns. Adding acid to water allows for better control and minimizes the risk of accidents.
Always add acid to water. This way if you splash what is in the container onto yourself it will be mostly water. The other way around, water to acid, and you would splash mostly acid onto yourself.
"Add acid to water and do what you ought-er" is the memory aid / jingle that my Freshman chemistry instructor used. It applies to most any acid.

Add the acid to the water, not the other way around.

is Ca(OH)2 is soluble in water and will hissing when hydrochloric acid is added
When an acid is added to a base, the pH decreases as the acid increases the concentration of hydrogen ions in the solution. This shift occurs because acids release H+ ions in water, leading to an increase in acidity.
When water is added to a strong acid or base, the concentration of the acid or base decreases because water dilutes the solution. This results in a less concentrated solution of the acid or base.
