Question

What is the total concentration of ions in a 0.10 M solution of barium chloride?

Answer 1

It is 0.30 because BaCl2 breaks into Ba+2 + 2Cl-... each on has 0.10 M so (0.10) + 2(0.10)= 0.30M

Answer 2

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

$BaCl_2(aq)\rightarrow Ba^{2+}(aq)+2Cl^-(aq)$

1 Mole of barium chloride gives 1 mole of barium ions and 2 moles of chloride ions.

Concentration of barium ions in solution = [x]

$[x]=1\times 0.10 mol/L=0.10 mol/L$

Concentration of chloride ions in solution = [y]

$[y]=2\times 0.10 mol/L=0.20 mol/L$

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.
