Explanation:
It is given that volume of is 300 mL and molarity is 0.200 M.
Volume of NaCl is 200 mL and molarity is 0.050 M.
The chemical reaction will be as follows.
for
is given as
.
As, molarity is number of moles present in liter of solution.
Hence, moles of (aq) will be calculated as follows.
moles of (aq) =
= 0.06 mol
=
= 0.120 M
Mole of =
= 0.010 M
Now, Q =
=
=
As, Q < hence, there will be no formation of
precipitate.
