Q. If there is 0.1M of AgNO3 and 0.01M of NaCl is there in a container separated by a semi permeable membrane. Will precipitate form ?if not , why ?
Precipitate will not be formed. because as it is separated by a semipermeable membrane osmosis occurs from higher concentration to lower concentration. That is from AgNO3 to NaCl. The balanced equation is
AgNO3(aq) + NaCl(aq) --->AgCl(s) + NaNO3(aq)
Therefore only 0.01 M of AgNO3 reacts with NaCl and forms a precipitate the remaining AgNO3 does not react.The amount of precipitate formed is negligible compard to the unreacted part.
