Question

For the titration of 60.0 mL of 0.300 M NH3 with 0.500 M HCl at 25 °C, determine the relative pH at each of these points Dete

Answer 1

Answer #1

1) NH3 is a basic compound, before adding HCl, the pH> 7.

2) The volume of HCl at the equivalence point is calculated:

V HCl = 0.3 M * 60 mL / 0.5 M = 36 mL

At the equivalence point, pH <7. Since it is a strong acid and a weak base.

3) Upon passing the equivalence point, the pH <7.

If you liked the answer, please rate it in a positive way, you would help me a lot, thank you.
