Question

Define the following:-
1. Strong Acid
2. Strong Base
3. Weak Acid
4. Weak Base

Answer 1

1 acid with high concentration eg. nitric acid
2 base with high concentration eg. sodium hydroxide
3 acid with low concentration eg acidic acid

Answer 2

Strong acid - The strength of an acid refers to its ability or tendency to lose a proton. A strong acid is one that completely ionizes in a solution. In water, one mole of a strong acid HA dissolves yielding one mole of H⁺ and one mole of the conjugate base, A−..

Strong base- A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution. 

Weak Acid - A weak acid is an acid chemical which does not dissociate (split into ions) completely in water solution. This means it does not give all its hydrogen ions into the water. Weak acidstypically have a pH between 3 and 6. 

Weak base - In chemistry, a weak base is a basethat does not ionize fully in an aqueous solution....
