Answer:
pH of the buffer solution is 1.76
Step-by-step explanation:
To find the pH of a buffer we can use Henderson-Hasselbalch equation:
pH = pKa + log [A⁻] / [HA]
Where pKa is -log Ka= 1.77 And [A⁻] is molar concentration of conjugate base, NaHSO₃ and [HA] molar concentration of weak acid, H₂SO₃
Replacing values of the problem:
pH = 1.77 + log [0.304M] / [0.310M]
pH = 1.76
pH of the buffer solution is 1.76
