Question

12. Predict whether the following will fully dissociate, partially dissociate, or not dissociate when dissolved in solution: (3 points) a a. Sodium sulfate, Na2S04(s), a strong electrolyte FULLY DISSOCIA TE b. Ethyl alcohol, CH CH2OHC), a nonelectrolyte ILL NOT DISSOCIATE c. Hypochlorous acid, HCIO(aq), a weak electrolyte PARTIALLY DISSOCIAT 13.Provide a balanced equation for the hydration of each compound in Problem 12. (3 points) a. b. C. 4. For the following ionic compounds, write a balanced equation for their hydration in water: (4 points) a. FeCl b. NaHCO3 c. K2SO4 d. Ca(NO3)2

Explanation / Answer

13. Balanced equations

a. Na2SO4

Na2SO4(s) + H2O(l) ---> 2Na+(aq) + SO4^2-(aq) + H2O(l)

b. CH3CH2OH

CH3CH2OH(l) ----> CH3CH2OH(aq)

c. HClO

HClO(aq) + H2O(l) --> H3O+(aq) + ClO-(aq)

---

4. hydration of ionic compounds

a. FeCl3

FeCl3(s) + H2O(l) --> Fe3+(aq) + 3Cl-(aq) + H2O(l)

b. NaHCO3

NaHCO3(s) + H2O(l) --> Na+(aq) + HCO3-(aq) + H2O(l)

c. K2SO4

K2SO4(s) + H2O(l) --> 2K+(aq) + SO4^2-(aq) + H2O(l)

d. Ca(NO3)2

Ca(NO3)2(s) + H2O(l) --> Ca2+(aq) + 2NO3-(aq) + H2O(l)
