Step 1

A salt refers to the product which is after the neutralization reaction between an acid and a base. Neutralization of a strong acid with a strong base will always result in the formation of a neutral salt.

According to the Bronsted-Lowery concept of acids and bases, an acid may be any chemical species which is capable of furnishing H+ ions in the aqueous solutions while base refers to the chemical species which is capable of accepting H+ ions in the aqueous solutions.

Step 2

Acidity and basicity of a given chemical species can be measured on the pH scale which is numbered from 1-14. When the pH is 7 , it means that the given compound is neutral , when the pH is less than 7 , it suggests that the compound is acidic in nature. If the pH is more than 7 , then the given compound is basic in nature. Lesser the pH of a given substance on the pH scale, more will be its acidic nature. More the pH on the pH scale , more basic is the nature of the given compound. Strong acids have low pH values (1-3) while strong bases have the pH value of about (11-14). On the other hand weak acids have the pH of about (4-6) while weak bases have pH in the range of (8-10).

Step 3

A salt is said to be acidic in nature which produces an acidic solution when it is dissolved in a solvent. These are mostly the salts produced by the reaction of a strong acid with a weak base. For example NH4Cl.

A salt is said to be basic in nature which when dissolved in a solvent produces a solution whose pH is greater than 7 or a solution which contains more OH- ions than the H+ ions. Such type ...
