Higher the amount of acid or base used to product a deinite change of pH in a buffer solution, higher will be its buffe capacity. Buffer capcity of solution is maximum under the following conditions [Salt] = [Acid](in acid buffer) [Salt] = [Base] (in base capacity] pH of buffer solution lies inthe range given below `pH = pH_(a) +-1` In other words,any buffer solution can be used as buffer up to two pH units only, depending upon the value of `pK_(a)` or `pK_(b)`. A buffer is said to be efficient when `pH = pK_(a)` or `pOH = pK_(b)` pH of `0.08 "mol" dm^(-3)` HOCl soluton is `2.85`. Calculate its ionization constant.A. `1.5 xx 10^(-5)`B. `2.5 xx 10^(-5)`C. `1.5 xx 10^(-8)`D. `2.25 xx 10^(-8)` |
