why would it become more concentrated?can u explain that please?
because ions from water are being electrolysed so sutomatically it will concentrate i thought first that water produced at anode would be suficent to replace lost water but it is not

The mass of one mole of a chloride formed by a metal Y is 74.5 g.
What is the formula of the chloride?

C YCl
D YCl 2

Since there will be no double displacement, for e.g if you chose to react KNO3 with HCl, the H wont be able to displace K nor will the Cl be able to displace NO3 hence no reaction will take place.[/quote
thanku :)

i guess coz both the products formed are soluble
e.g
KNO3(aq)+HCl(aq)--->KCl(aq)+HNO3(aq)
KNo3(aq)+AgCl(s)--->KCl(aq)+AgNO3(aq)
its not suitable as we cant seperate them....
(correct me if m wrong)
in titration method reactants are all soluble.
