Concentrated acids should always be added slowly to water with constant stirring to prevent splashing and excessive heat generation.

The process is highly exothermic, and if not done carefully, it can lead to splashing, burns, or even breakage of glass containers due to excessive local heating.

It is advised to never taste or touch alkalis as they are soapy to touch, bitter, and corrosive, posing potential harm.

An alkali is a base that specifically dissolves in water. This characteristic sets alkalis apart from other bases, which may not necessarily dissolve in water.

The experiment suggests that hydrogen ions in HCl are produced in the presence of water, indicating that the separation of H+ ion from HCl molecules requires water.
