Saccharin (Ka=2×10−12) is a weak acid represented by formula HSaC. – InterviewSolution

1.	Saccharin (Ka=2×10−12) is a weak acid represented by formula HSaC. 4×10−4 moles of saccharin are dissolved in 200 cc buffer of pH 3. Assuming no change in volume, calculate the concentration of saC−1 ions in the resulting solution at equilibrium. (Assume jpH of buffer is maintained)
Answer» Saccharin $(K_{a} = 2 \times 10^{- 12})$ is a weak acid represented by formula HSaC. $4 \times 10^{- 4}$ moles of saccharin are dissolved in 200 cc buffer of pH 3. Assuming no change in volume, calculate the concentration of $s a C^{- 1}$ ions in the resulting solution at equilibrium. (Assume jpH of buffer is maintained)
