The equation for weak acid and weak base is given as-

pH=7+ $\frac{1}{2}$  ?(pKa?−pKb?)

K_a=1.8×10^-5

pK_a=−log (1.8×10-5) =5−log1.8 =4.744

pK_b?=−log (1.8×10-5) =4.744

pH=7+ $\frac{1}{2}$  ?(pKa?−pK_b?) =7

2H₂O₂ → 2H₂O+O₂

5 volume H₂O₂ means IL of H₂O₂ will give 5L of O₂ at STP.

On the basis of the equation it is clear that 22.7 L of O₂ is produced by 68 g of H₂O₂.

5L of O₂ is produced by = $\frac{68g\times 51}{22.71}$  = $\frac{3400}{227}$ = g of H₂O₂=14.9g

i.e. 15 g H₂O₂ dissolved in 1 L solution will give 5 L oxygen or 1.5 g H₂O₂/100 mL solution will give 500 mL oxygen. Thus 15 g/L or 1.5% solution is known as the 5V solution of H₂O₂.

pH for weak acid is given by the following equation:

pH= $\frac{1}{2}$ [pK_a−logC]

= $\frac{1}{2}$ [−log (1.74×10⁻⁵)−log0.01]

=3.4
