Answer to Question #183675 in General Chemistry for sard

Question

8.0 mL of 0.10 M HC2H3O2 is titrated with 0.10 M NaOH. Perform the following calculations

1. pH of the acid before any NaOH is added 
2. Volume of 0.10 M NaOH needed to reach the equivalence point
3. pH at the equivalence point
4. Volume of 0.10 M NaOH needed to reach the half-way point
5. pH at the half-way point

Answer 1

pH of the acid before any NaOH is addedi is

$pH = -log (0.10)=1$

Volume of 0.10 M NaOH needed to reach the equivalence point= 0.04398 L0.04398L

$pH = 7.00$
