Description : A solution which resists change in its pH value on addition of acid/alkali is called the __________ solution. (A) Neutral (B) Ideal (C) Buffer (D) Zero pH
Last Answer : Option C
Description : Buffer solutions have constant acidity and alkalinity because: (1) they have fixed value of pH (2) these give unionised acid or base on reaction with added acid or alkali (3) acids and alkalies in these solutions are shielded from attack by other ions (4) they have large excess of H+ or OH– ions
Last Answer : these give unionised acid or base on reaction with added acid or alkali
