Answer 1

Answer:

Acids-

2. It has pH less than 7.

3. It is corrosive in nature and turns blue litmus red.

Bases-

1. Release hydroxide ions in aqueous solutions.

2. It has pH greater than 7.

3. It turns red litmus paper blue.

Salts-

1. Ionic compound formed by neutralisation reaction that takes place between an acid and a base.

2. It has both cations and anions and is neutral in nature.

3. Most of them can be electrolysed and it dissociates into its component ions when placed in water.

Answer 2

Answer:

Acid - It is a chemical substance that can give proton or hydrogen ion. In a solution, it has a pH below 7. The high concentration of hydrogen ion is produced by acid and. Acid can be strong such as sulfuric acid $\mathrm{H}_{2} \mathrm{SO}_{4}$ and it can be weak such as Nitrous acid  

Base- It’s a chemical substance that can donate hydroxide ion ($\mathrm{OH}^{-}$) in a solution it has a pH above than 7. Example of a strong base is Sodium hydroxide (NaOH) and a weak base is Ammonia ($\mathrm{NH}_{3}$).

Salt- It is a mineral made by sodium and chloride and they are found in crystalline form. Sodium chloride (NaCl) is the common table salt.
