Question

write the formula to calculate pH of buffer solution​

Answer 1

Answer:

Calculating pH of Buffer Solutions

1. [H3O+]=Ka×[HA][A−]
2. −log [H3O+]=−log Ka−log[HA][A−]
3. pH=pKa+ log[A−][HA]
4. [CH3COOH][CH3COO−]
5. [H3O+]=Ka[CH3COOH][CH3COO−]

Answer 2

Answer

Calculating pH of Buffer Solutions

1.[H3O+]=Ka×[HA][A−]

2.−log [H3O+]=−log Ka−log[HA][A−]

3.pH=pKa+ log[A−][HA]

4.[CH3COOH][CH3COO−]

5.[H3O+]=Ka[CH3COOH][CH3COO−]
