Chapter 7: Q17P (page 159)

Describe the chemistry that occurs in each of the following regions in Figure 7-2:
before the equivalence point;
(ii) at the equivalence point; and
(iii) past the equivalence point.
Write the equation to find $[{Ag}^{+}]$ in each region.

Short Answer

Expert verified

The equation to find $[A g^{+}] i s C_{t i t r a n t =} \frac{n_{t i t r a n t} - n_{a n a l y t e}}{V_{t o t a l}} [A g^{+}] = \frac{n_{A g^{+}} - n_{1^{-}}}{V_{A g +} + V_{1^{-}}}$

Step by step solution

Define The formula to be used for solution

Solve for $[l^{-}]$

role="math" localid="1654772439398" $C_{a n a l y t e =} \frac{n_{a n a l y t e} - n_{t i t r a n t}}{V_{t o t a l}} [l^{-}] = \frac{n_{1^{-}} - n_{A g^{+}}}{V_{1^{-}} + V_{A g^{+}}}$

calculate the solubility

Here for $[{Ag}^{+}]$ can be calculated using the solubility product formula:

role="math" localid="1654772931130" $K_{sp} = [{Ag}^{+}] l^{-} [{Ag}^{+}] = \frac{K}{[l^{-}]}$

(ii) at the equivalence point and by letting $[l^{-}]$ be equal to $[{Ag}^{+}]$

$[{Ag}^{+}] [l^{-}] = K_{sp} [{Ag}^{+}] [{Ag}^{+}] = K_{sp} {[{Ag}^{+}]}^{2} = K_{sp} [{Ag}^{+}] = \sqrt{K_{sp}}$

The number of moles of titrant $({Ag}^{+})$ is greater than the number of moles of analyte $(l^{-})$ .

$C_{t i t r a n t =} \frac{n_{t i t r a n t} - n_{a n a l y t e}}{V_{t o t a l}} [A g^{+}] = \frac{n_{A g^{+}} - n_{1^{-}}}{V_{A g +} + V_{1^{-}}}$
