Chapter 4, Problem 114CWP

Interpretation Introduction

Interpretation:

Calculate the mass of solid when given barium chloride and sodium phosphate is mixed.

Concept Introduction:

The precipitate will be formed when two soluble salt solutions combined together is called as a precipitation reaction.

The balanced equation is

${\text{3BaCl}}_{\text{2(aq)}}{\text{+2Na}}_{\text{3}}{\text{PO}}_{\text{4(aq)}}\to {\text{Ba}}_{\text{3}}{{\text{(PO}}_{\text{4}}\text{)}}_{\text{2(s)}}{\text{+6NaCl}}_{\text{(aq)}}$

Formula

$\text{Mole=}\frac{\text{volume}\text{of}\text{solution (L)×molarity (M)}}{\text{litre (L)}}$ (1)
