Question

calculate the pH of the hydrochloric acid solution at the following points during titration. using answer from 5a (concentration of 0.2M HCl = 0.07292g HCl/0.010L) A) starting point B) after 8.00mL of base has been added C) at the equivalence point calculate the pH of the hydrochloric acid solution at the following points during titration. using answer from 5a (concentration of 0.2M HCl = 0.07292g HCl/0.010L) A) starting point B) after 8.00mL of base has been added C) at the equivalence point calculate the pH of the hydrochloric acid solution at the following points during titration. using answer from 5a (concentration of 0.2M HCl = 0.07292g HCl/0.010L) A) starting point B) after 8.00mL of base has been added C) at the equivalence point

Explanation / Answer

A) starting point :

[H+] = 0.2 M

pH = -log [H+] = -log (0.2)

pH = 0.70

B)   after 8.00mL of base has been added.

for this problem base concentration is needed

C) at the equivalence point

at this poiint acid moles = base moles . if both are strong . the salt is neutral .

pH = 7.0
