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)` The solubility product of `Al(OH)_(3)` is `2.7 xx 10^(-11)`. Calculate its solubility in `gL^(-1)` and also find out pH of this solution. (Atomic mass of `Al = 27u`).A. `11.47`B. `2.55`C. `10.6`D. `3.5` |
