Question

Give an example of a weak acid and an example of a strong acid. What is the difference between them in terms of reactivity?

Answer 1

Strong acid :- A strong acid is an acid that ionizes completely in an aqueous solution. For example; HCl, H2SO4, HNO3 etc

Strong acids will always show strong conductivity. Strong acids usually pass more current as compared to the weak acids for the same voltage and concentration.

Weak acid :- A weak acid is one that ionizes partially in a solution. For example :- CH3CHOOH,HF, C6H5COOH etc.

Weak acids have a low conductivity. They are poor conductors and show a low value for current passing.
