Answer : The molarity of chloride anion in the solution is 0.05 mole/L
Explanation : Given,
Mass of = 0.701 g
Volume of solution = 50 ml = 0.050 L
Molarity of AgCl = 55.0 mM = 0.055 M
Molar mass of = 126.751 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react with 1 mole of
So, 0.00275 moles of react with
moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and
is a limiting reagent and it limits the formation of product.
Now we have to calculate the moles of .
As, 2 moles of react to give 2 moles of
So, 0.00275 moles of react to give 0.00275 moles of
Now we have to calculate the molarity of .
As we know that, 1 mole of AgCl in solution gives 1 mole of silver ion and 1 mole of chloride ion.
So, the molarity of chloride ion = Molarity of AgCl = 0.05 mole/L
Therefore, the molarity of chloride anion in the solution is 0.05 mole/L
