InterviewSolution

1.	The empirical formula of a commercial ion exchange resin is C8H7SO3Na(M.M=206). The resin can be used to soften water according to the reaction:Ca2++2C8H7SO3Na→Ca(C8H7SO3)2+2Na+What would be the maximum uptake of Ca2+ by the resin expressed in mol/g of resin?
Answer» The empirical formula of a commercial ion exchange resin is $C_{8} H_{7} S O_{3} N a (M . M = 206)$ . The resin can be used to soften water according to the reaction: $C a^{2 +} + 2 C_{8} H_{7} S O_{3} N a \to C a (C_{8} H_{7} S O_{3})_{2} + 2 N a^{+}$ What would be the maximum uptake of $C a^{2 +}$ by the resin expressed in $mol/g$ of resin?
