Calcium lactate is a salt of weak acid i.e., lactic acid having general formula Ca(Lac)2. Aqueous solution of salt has 0.3 M concentration. pOH of solution is 5.60 . If 90% of the salt is dissociated then what will be the value of pKa ?
- 2.8 – log (0.54)
- 2.8 + log (0.54)
- 2.8 + log (0.27)
- None of these
Answer
(A) 2.8 – log (0.54)
