Write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of nickel(II) nitrate and potassium sulfide are combined


Expert Answer

Step 1

The precipitation reaction for nickel(II) nitrate and potassium sulfide can be shown as:

Ni(NO3)2 + K2S  ->   NiS + 2 KNO3

Step 2

Nickel(II) nitrate on getting reacted with potassium sulfide produces nickel sulfide and potassium nitrate.

Step 3

Nickel present in +2 state in nickel(II) nitrate which on getting combined ...
