A) \[{{H}_{2}}O(l)\xrightarrow[{}]{{}}{{H}^{+}}(aq)+O{{H}^{-}}(aq)\]
B) \[N{{H}_{4}}Cl(s)\xrightarrow[{}]{{}}NH_{4}^{+}(aq)+C{{l}^{-}}(aq)\]
C) \[CuS{{O}_{4}}\cdot 5{{H}_{2}}O(s)+{{H}_{2}}O\xrightarrow[{}]{{}}CuS{{O}_{4}}(aq)\]
D) \[CuS{{O}_{4}}(s)+5{{H}_{2}}O\xrightarrow[{}]{{}}CuS{{O}_{4}}\cdot 5{{H}_{2}}O(s)\]
Correct Answer: C
Solution :
| [c] \[{{H}_{2}}O(l)\xrightarrow[{}]{{}}{{H}^{+}}(aq)+\overset{\Theta }{\mathop{OH}}\,(aq)\] |
| Enthalpy of dissociation |
| \[N{{H}_{4}}Cl(s)\xrightarrow[{}]{{}}NH_{4}^{+}(aq)+C{{l}^{-}}(aq)\] |
| Enthalpy of dissociation |
| \[CuS{{O}_{4}}\cdot 5{{H}_{2}}O(s)+{{H}_{2}}O\xrightarrow[{}]{{}}CuS{{O}_{4}}(aq)\] |
| Enthalpy of solution |
| \[CuS{{O}_{4}}(s)+5{{H}_{2}}O\xrightarrow[{}]{{}}CuS{{O}_{4}}\cdot 5{{H}_{2}}O(s)\] |
| Enthalpy of hydration |
