Calculate [HY^3-] in a solution prepared by mixing 10.00 mL of 0.010 0 M VOSO₄, 9.90 mL of 0.010 0 M EDTA, and 10.0 mL of buffer with a pH of 4.00

Short Answer

Expert verified

The concentration of HY^3- in solution is 4.6脳10^-11M

Step by step solution

Given Information

Volume of VOSO₄ taken to prepare solution = 10 mL

Concentration of VOSO₄ taken to prepare solution = 0.01M

Volume of EDTA taken to prepare solution = 9.90 mL

Concentration of EDTA taken to prepare solution = 0.01M

Volume of buffer (pH=4) solution taken=10 mL

Determine concentration of VO2+ and VOY2-

$\begin{matrix} [V O^{2 +}] = (\frac{0.1}{29.9}) (0.01 M) \\ = 3.34 脳 10^{鈭� 5} M \\ [V O Y^{2 鈭�}] = (\frac{9.9}{29.9}) (0.01 M) \\ = 3.31 脳 10^{鈭� 3} M \end{matrix}$

Equations and data obtained in order to proceed for calculation are as follows

$\begin{matrix} K_{f} = 10^{18.7} \\ A t 鈥夆赌夆赌� p H 鈥夆赌夆赌� 4 鈥夆赌� p K_{6} = 10.37 鈥� (f o r 鈥� H_{6} Y^{2 +}) \end{matrix}$

Determine concentration of HY3-

$\begin{matrix} K_{f} = \frac{[V O Y^{2 鈭�}]}{[V O^{2 +}] [Y^{4 鈭�}]} \\ [Y^{4 鈭�}] = \frac{[V O Y^{2 鈭�}]}{[V O^{2 +}] K_{f}} \\ = \frac{[3.31 脳 10^{鈭� 3}]}{[3.34 脳 10^{鈭� 5}] 脳 10^{18.7}} \\ = 1.98 脳 10^{鈭� 17} \end{matrix}$

$\begin{matrix} K_{6} = \frac{[H^{+}] [Y^{4 鈭�}]}{[H Y^{3 鈭�}]} \\ [H Y^{3 鈭�}] = \frac{[10^{鈭� 4}] [1.98 脳 10^{鈭� 17}]}{[10^{鈭� 10.37}]} \\ = \frac{[H^{+}] [Y^{4 鈭�}]}{K_{6}} \\ = 4.6 脳 10^{鈭� 11} M \end{matrix}$

Therefore,the concentration of HY^3- in solution is 4.6脳10^-11M
