Hi, in this question we are given that m2 plus ion combines with 2scn minus ion to produce mscn whole twice.
00:09
The initial concentration of these two ions are given in this manner and the equilibrium concentration of mscn whole twice is given as 2 into 10 raised to power minus 5 molar.
00:20
We are asked to calculate the equilibrium concentration of m2 plus ion, scn minus ion and the kc value that is the equilibrium constant value.
00:30
Here we need to draw the i's table where i represent the initial concentration, cd represents the change in concentration and e represents the equilibrium concentration.
00:41
We can say that initially we are given with these concentrations and there is no formation of mscn whole twice.
00:48
After some time there would be change of minus x molar concentration from this initial concentration and from this there will be change of minus 2x and here there will be formation of plus x molar.
01:03
At equilibrium we are having 0 .000100 minus x molar concentration for m2 plus ion and for scn 2 minus ion it will be 0 .000250 minus 2x and here it will be x only.

We are given that at equilibrium the concentration of mscn whole twice is 2 into 10 raised to power minus 5 molar...
