What is pH of solution containing 50 ~mL each of 0.1 M sodium acetate and 0.01 M acetic acid? ( pK _ a CH ₃ COOH =4.50 )
Options
- A2.5
- B3.5
- C4.5
- D5.5
Correct answer
D. 5.5
Step-by-step solution
For acidic buffer solution aligned & pH = pK _ a + ₁₀ [ Salt ] [ Acid ] ; & pH =4.50+ ₁₀ 0.1 0.01 & pH =4.50+ 10 ; pH =5.50 aligned
