1.A weak acid of dissociation constant 10−510^{-5}10−5 is being titrated with aqueous NaOH solution. The pH at the point of one-third neutralisation of the acid will be:a.5+log2−log35 + \log 2 - \log 35+log2−log3b.5−log25 - \log 25−log2c.5−log35 - \log 35−log3d.5−log65 - \log 65−log6Login to continueOnly logged in users canattempt or see the solution.
