Question

Which of the following do you think is a correct statement?

(a) Ammonium hydroxide / ammonium chloride is an acidic buffer

(b) boric acid / borax is an acidic buffer

(c) henderson hasselbalch equation is given by pH = pKb + log[salt]/[acid]

(d) PH + pOH = 4

The question was posed to me in an online quiz.

My query is from Equilibrium topic in division Equilibrium of Chemistry – Class 11

Answer 1

The correct option is (b) boric acid / borax is an acidic buffer

For explanation: Ammonium hydroxide / ammonium chloride is a basic buffer, henderson hasselbalch equation is given by pH = pKa + log[salt]/[acid] and pH + pOH = 14. So the only correct statement is that boric acid / borax is an acidic buffer.
