PART 4: Co(H2O)6(+2) + 4Cl(-1) --> CoCl4(-2) + 6H2O

Write eqautions for # 2, 4, 8, 9

2. Water added to CoCl2(6H2O)(s) and produces Co(2+)(aq) ion

4. Distilled water into CoCl4(-2)(aq) and produces Co(2+)(aq) ion

8. Heat up tube with CoCl2(6H20)(s) crystals (just enough to cover the crystals, not dissolve them). produces CoCl2 (s) residue

9. Distilled water added to CoCl2 (s) and produces Co(2+)(aq)

Explanation / Answer

2.

CoCl2(6H2O)(s)   -------> Co2+ (aq) + 2Cl- (aq) + 6H2O(l)

4.

COCl42- (aq) ----> Co2+ (aq) +   4Cl- (aq)

8.

CoCl2(6H2O)(s)   ----> COCl2 (s) + 6 H2O (l)

9.

COCl2 (s) ---> Co2+ (aq) + 2Cl- (aq)
