1. Two HCl(aq) solutions have pH= 2.00 and pH= 3.00, respectively. If equal volumes of these two solutions are combined, the pH of the resulting solution wil be ...(adsbygoogle = window.adsbygoogle || []).push({});

Now I know the answer is 2.26 but I don't know how to actually solve it..

2.Aniline(C6H5NH2) is a weak base. At 25C, a 0.100M aqueous solution has a pH of 8.80. The Kb of aniline is..

Now I know the answer is 4.0x10^-10 but I don't know how to actually solve it..

3. 60.0ml of .100 M KOH is mixed with 40.0ml of .250M HCl at 25C. Assuming the volumes are additive, what is the pH of the resulting solution?

1.4 but I don't know how to solve it..

Please tell me how to do those..I have a chem test tomorrow

TIA..
