The question deals with the solubility of a2x3.
00:07
It is a salt and we have a general formula or general representation to indicate the dissociation or the equilibrium that exists between a salt ax, b ,y and that would be with its ions x -a -y -y -y -plus plus y -b -x -minus.
00:36
It may usually seem a bit complicated but it's very easy.
00:41
While balancing the sides of left hand and right hand sides, we can see that since there is x here, a should be x.
00:54
And since there is y in the left hand side, there should be y in order to balance the sociology.
01:01
And the charges will be exchanging.
01:04
Y will be given to the a as charge and x will be given to b as.
01:09
Charge.
01:09
There will be taking a place an exchange of x and y.
01:13
That is happening in this case.
01:15
This is a general formula of any salt of the form a xby.
01:19
We can directly substitute this formula into the salt that we need, a2x3...
