# 7) How many ml of 0- 8) Determine if a precipitate occurs upon mixing.docx

7) How many ml of 0. 8) Determine if a precipitate occurs upon mixing the following solutions. If a precipitate does occur, give the correct net ionic equation: a) BaCI, and CuSO b) NaNO, and ZnCl, c) KOH and NiCl,
Solution
Solution:
The net ionic equation for the precipitates as given below,
a) BaCl 2 and CuSO 4
BaCl 2 + CuSO 4 --> BaSO 4 + CuCl 2
Precipitate = BaCl 2 white precipitate
CuCl 2 = blue colour solution
b) NaNO3 and ZnCl4
No reaction forms
c) KOH and NiCl 2
2KOH + NiCl 2 --> KCl 2 + Ni(OH) 2
No precipitate forms
.
