Question

Calculate concentration of a solution of HCI if the solution has a pH of 3.0. V hat is the pOH of the solution? What is equivalent point in a titration of acid and base? And what you expect to be the pH of the solution at the equivalent point in a titration of SA with SB, VVA with SB, and WB with SA? The following graph shows titration of a week acid with a strong base Using this graph estimate the pK_aof the acid For full credit explain in detail and draw the necessary lines. On one graph, draw titration curves for titration of a 0.1 molar strong acid if one sample of that was titrated with a 0.1 molar strong base and another sample of the same acid titrated with 0.2 molar of the same base Show initial pH, EP and final pH for both curves.

Explanation / Answer

1.

Concentration of HCl

pH = -log(H3O+)

[H3O+] = 10-pH = 10-3 = 0.001 M

concentration of HCl is 0.001 M

calculation of pH

there is a direct formula

pH + pOH = 14

pOH = 14-pH

pOH = 14-3 = 11

pOH = 11
