Introduction
Salts salts are formed by the reaction take place between acid and base.Acid Acids are substance that releases H+ ions in aqueous solution.Base substance that releases OH- ion in aqueous solution.

Acid
The ability to turn blue litmus red, and the ability to react with bases and certain metals (like calcium) to form salts.
A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ion in the solution. Chemicals or substances having the property of an acid are said to be acidic.
Acids are sour in taste. Acids are corrosive in nature.

Base
They are slippery to touch, taste bitter, change the color of indicator red litmus paper blue, react with acids to form salts.
A higher PH means strong base. Value of base starts from 8-14.
This has concentrated of OH- ions.

Salt
Salts are ionic compounds that result from the neutralization reaction of an acid and a base.
They are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge).
Some examples
acid + base salt + water
NaOH + Hcl NaCL + H2O

Uses
Used in processes to make products including plastics, soaps rayon and
textiles. Removal paint. Etching aluminum. Dehorning of cattle. During two steps of the paper making process. Used in relaxers to help straighten hair however this is
becoming less popular because of the possibility of chemical burns.
