A buffer solution is prepared by mixing 0.01 M weak acid and 0.05 M solution of a salt of weak acid and strong base. What is the pH of buffer solution? ( pKa =4.74)

Options

  1. A3.34
  2. B4.80
  3. C5.44
  4. D6.93

Correct answer

C. 5.44

Step-by-step solution

aligned pH & = pK _ a + ₁₀ [ salt ] [ acid ] & =4.74+ ₁₀ 0.05 0.01 & =4.74+0.7=5.44 aligned
