Chapter 23: Q13P (page 629)

For a given value of ${[HL]}_{org}$ in Equation 23-13, over what pH range (how many pH units) will D change from if n = 2?

Short Answer

Expert verified

$鈭� pH = 2$

Step by step solution

Given Information:

Distribution change pH value for D =0.01 to 100 as n = 2

To Find the[HL]org :

For distribution of metal-chelate complex between phases is

$D = \frac{K_{M} {尾碍}_{a}^{n}}{K_{L}^{n}} \frac{{[HL]}_{org}^{n}}{{[H^{+}]}_{aq}^{n}}$

${ML}_{n}$ is the form extracted into organic solvent

For distribution coefficients as localid="1654772730303" $D_{1} = 0.01$

$0.01 = \frac{K_{M} {尾碍}_{a}^{n}}{K_{L}^{n}} \frac{{[HL]}_{org}^{n}}{{[H^{+}]}_{aq}^{n}} As D_{2} = 100 100 = \frac{K_{M} {尾碍}_{a}^{n}}{K_{L}^{n}} \frac{{[HL]}_{org}^{n}}{{[H^{+}]}_{aq}^{n}} \frac{D_{2}}{D_{1}} = \frac{\frac{K_{M} {尾碍}_{a}^{n}}{K_{L}^{n}} \frac{{[HL]}_{org}^{n}}{{[H^{+}]}_{2}^{n}}}{\frac{K_{M} {尾碍}_{a}^{n}}{K_{L}^{n}} \frac{{[HL]}_{org}^{n}}{{[H^{+}]}_{1}^{n}}}$

For n = 2 in the equation and to eliminate the values to simplify the equation

$\frac{D_{2}}{D_{1}} = \frac{\frac{K_{M} {尾碍}_{a}^{n}}{K_{L}^{n}} \frac{{[HL]}_{org}^{n}}{{[H^{+}]}_{2}^{2}}}{\frac{K_{M} {尾碍}_{a}^{n}}{K_{L}^{n}} \frac{{[HL]}_{org}^{n}}{{[H^{+}]}_{1}^{2}}} \frac{D_{2}}{D_{1}} = {(\frac{{[H^{+}]}_{1}}{{[H^{+}]}_{2}})}^{2} \frac{100}{0.01} = {(\frac{{[H^{+}]}_{1}}{{[H^{+}]}_{2}})}^{2} \sqrt{10^{4}} = (\frac{{[H^{+}]}_{1}}{{[H^{+}]}_{2}}) 10^{2} = (\frac{{[H^{+}]}_{1}}{{[H^{+}]}_{2}})$

To calculate △pH

$鈻� pH = - \log (\frac{{[H^{+}]}_{1}}{{[H^{+}]}_{2}}) 鈻� pH = - \log (10^{2}) 鈻� pH = 2$
