the equation will look like this: pH=7.20+log 0.4/0.2 = 7.50 Yes?
Sorry the final pH of the mixture is 7.50, is that correct DrBob222?
you know the pH of HNO3 to be 3.4 use pH=-log [] 10^-3.4= ?
pH=7.20+log 0.2M/ 0.4M pH=7.20+(-0.30) pH=6.69 I'm heading in the right direction?
pH=7.20+log0.1M/0.1M pH=7.20
pH= pKa + log 0.1M/0.1M what's the pKa value?
what's the pKa?
