Why alkali metals are not found in nature? |
|
Answer» Alkali metals have only one electron in there valence shell which they easily lose and they bigger in size so there ionization enthalpies is low .therefore they highly reactive and this reason is alkali metals not found in nature. Because alkali metals are very reactive so they can react easily with environment yeah yo |

What is salt hydrolysis..?? |
| Answer» Salt Hydrolysis:- Hydrolysis is a reaction involving the breaking of a bond in a molecule using water. The reaction mainly occurs between an ion and water molecules and often changes the pH of a solution. There are three main types of hydrolysis: salt hydrolysis, acid hydrolysis, and base hydrolysis.The cations or anions formed during ionization of salts either exist as hydrated ions in aqueous solutions or interact with water to regenerate the acids and bases. The process of interaction between cations or anions of salts and water is known as hydrolysis of salts. | |
