Question

NiSO4 reacts with with Na3PO4 to give a yellow green precipitate of Ni3(PO4)2 and a solution of Na2SO4.? 3NiSO4(aq) + 2Na3PO4(aq) ---------------> Ni(PO4)2 (s) + 3Na2SO4 (aq) 
How many mL of 0.375M NiSO4 will react with 45.7 mL of 0.265M Na3PO4? 

Pls help.

Answer 1

let V ml of NiSO4 is required
N1V1 = N2V2
N = M*valency factor
2*0.375*V = 3*45.7*0.265
V = 48.442 ml
