0 mL sample of 0.20 M HCl( aq )is titrated with 20.0 mL of 0.10 M NaOH( aq ) (adding NaOH to HCl).

A 50.0 mL sample of 0.20 M HCl(aq) is titrated with 20.0 mL of 0.10 M NaOH(aq) (adding NaOH to HCl). Determine which region on the titration curve the mixture produced is in, and the pH of the mixture.  Assume that the volumes of the solutions are additive. 

1) After adding the NaOH solution, the mixture is             

[ Select ] ["after", "at", "before"] the equivalence point on the titration curve. 

2) The pH of the solution after adding NaOH is             

[ Select ] ["0.94", "7.00", "13.06", "2.10"]
