Question 10:

Explain the differences between acid and base.

Open in App

Solution

Basis

Acid

Base

Definition

An acid is any chemical compound once dissolved in water produces a solution with hydrogen ion activity more than purified water

A base is an aqueous substance that could absorb hydrogen ions.

Strength

Relies on the concentration of the hydronium ions

Relies on the concentration of the hydroxide ions

Examples

Acetic acid CH3COOH and sulphuric acid

Sodium Hydroxide (NaOH) and Ammonia

Characteristics (Physical)

Would depend upon the temperature, acids would look solid, liquid or in the form of gas. It would also have a sour taste.

Bases would feel slippery and solid in nature except ammonia which is gaseous. It would have a bitter taste.

Disassociation

Acids would release hydrogen ions (h+) when mixed with water

Bases would release hydroxide ions(OH-) when mixed with water

Test with Litmus

Would turn litmus paper red

Would turn litmus paper blue
