Chapter 21: Q21.145 CP (page 979)

Use Appendix D to calculate the $K_{sp}$ of AgCl.

Short Answer

Expert verified

The value is obtained as: $K_{sp} {=1.90脳10}^{- 4}$

Step by step solution

Define chemical reaction

Chemical synthesis or, alternatively, chemical breakdown into two or more separate chemicals occurs when one component interacts with another to generate new material. These processes are known as chemical reactions, and they are generally irreversible until followed by other chemical reactions.

Evaluate the value of Ksp

Silver is oxidized during the production of AgCl.

${Reaction: Ag}_{(s)} {+ Cl}_{(aq)}^{-} 鈫� {AgCl}_{(s)} {+e}^{-} E_{half - cell}^{0} = - 0.22 鈭� G^{o} {= - nFE}_{C e l l}^{0} {= - 1e}^{-} 脳96,500 \frac{C}{{mole}^{-}} 脳-0.22痴 = 21, 230 J$

$鈭� G^{o} = - RTlnK$ in Action the $K_{sp}$ for AgCl may be calculated as:

$\begin{array}{rcl} 21,230J = - RTlnK \\ lnK = \frac{- 21,230J}{RT} \\ K_{sp} = e \frac{- 21,230}{RT} \\ = e \frac{- 21,230}{298 K脳8.314 \frac{J}{mol K}} \\ {= 1.90脳10}^{- 4} \end{array}$

Therefore, the value is: $K_{sp} {= 1.90脳脳10}^{- 4}$
