Answer:
0.30 M is the total concentration of ions in a 0.10 M solution of barium chloride.
Explanation:
Concentration of solution of barium chloride = 0.10 M = 0.10 mol/L
[tex]BaCl_2(aq)\rightarrow Ba^{2+}(aq)+2Cl^-(aq)[/tex]
1 Mole of barium chloride gives 1 mole of barium ions and 2 moles of chloride ions.
Concentration of barium ions in solution = [x]
[tex][x]=1\times 0.10 mol/L=0.10 mol/L[/tex]
Concentration of chloride ions in solution = [y]
[tex][y]=2\times 0.10 mol/L=0.20 mol/L[/tex]
Total concentration of ions in the solution : [x]+[y]
0.10 mol/L + 0.20 mol/L = 0.30 mol/L
0.30 M is the total concentration of ions in a 0.10 M solution of barium chloride.
