Question

Distinguish between acid strength and acid concentration.

Answer 1

(i) Acid strength:- It indicates whether acid is weak acid or strong acid.

(ii) Concentration:- The concentration of a solution is a measure of the number of particles of the solute in the solvent.

(iii) A strong acid does not become a weak acid just because it is diluted. Examples: Concentrated $HCl$ acid and dilute $HCl$ acid are both strong acids because they are both completely ionized in water.

(iv) A strong acid and a weak acid of same concentration will react at different rates with same metal.
