0 mL sample of 0.25 M NaOH( aq )is titrated with 40.0 mL of 0.10 M HCl( aq ) (adding HCl to NaOH).

A 10.0 mL sample of 0.25 M NaOH(aq) is titrated with 40.0 mL of 0.10 M HCl(aq) (adding HCl to NaOH). 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 HCl solution, the mixture is             

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

2) The pH of the solution after adding HCl is             

[ Select ] ["10.83", "1.52", "7.00", "2.82"]
