Buffer capacity of a buffer is given as two units for a change in pH by Unity. Then what is the number of moles of acid or base, added in one litre of the solution?(a) 2(b) 0.5(c) 1(d) 4I had been asked this question in an international level competition.I'm obligated to ask this question of Equilibrium topic in chapter Equilibrium of Chemistry – Class 11

Answer»

Right choice is (a) 2

The explanation: Buffer capacity is denoted by Φ = NUMBER of MOLES of acid or base ADDED to one litre of the buffer by a change in PH. Here the change in pH is given by 1 and the buffer capacity is given by 2, therefore by substituting, we get that 2 moles of acid or base are added in one litre of the solution.
