Solution:
Since with LiBr no precipitation takes place therefore Ag+ is absent
Here on adding to it precipitation takes place.
Precipitate is as follows,
Thus,
is present
When is added again precipitation takes place.
Therefore the reaction is as follows,
Therefore,
are present in the solution
Answer: Concentration of the chemist's sodium chloride solution is 34.4 mol/L.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n= moles of solute
= volume of solution in ml
Given : moles of = 6.89
volume of solution = 200 ml
Putting in the values we get:
Thus the concentration of the chemist's sodium chloride solution is 34.4 mol/L.
