Explanation The reaction by which silver, AgCl dissolves into its constituent aqueous ions is as follows: A g C l ( s ) ⇌ A g + ( a q ) + C l − ( a q ) ⇋ A g C l ( s ) ⇌ A g + ( a q ) + C l − ( a q ) The expression for the solubility product constant K s p for AgCl is as follows: K s p = [ A g + ] [ C l − ] The ICE table is [ A g + ] [ C l − ] I n i t i a l 0.00 0.00 C h a n g e + S + S E q u i l l i b r i u m S S Substituting the equilibrium pressure for [ A g + ] a n d [ C l − ] into expression for K s p : K s p = [ A g + ] [ C l − ] = ( S ) ( S ) = S 2 Substitute the numerical value of S for silver chloride (AgCl) to calculate the K s p as follows: K s p = S 2 K s p = ( 1.33 × 10 − 5 ) 2 = 1.77 × 10 − 10 Thus, the solubility product constant K s p will be 1.77 × 10 − 10 a t 23 ° C . Calculate the solubility at 50°C: ln K 2 K 1 = − Δ H º R ( 1 T 2 − 1 T 1 ) Here, the standard enthalpy change ( Δ H º ) = 65.7 kJ/mol Gas constant ( R ) = 8.314 J ( m o l K ) Temperature { ( T 1 ) = 25 + 273 ( T ( K ) = T ( º C ) + 273 ) = 298 K ( T 2 ) = 50 + 273 ( T ( K ) = T ( º C ) + 273 ) = 323 K Equilibrium c o n s t a n t s ( K 1 = K s p = 1
