So here i've written down the general equation and when considering the dissociation of solid.
00:12
So if you have one element and there's so many of it, that's represented by x and the element is m.
00:22
And you have another element and that's represented by n, y, and this is solid.
00:28
And then they split up and the number of x over here will become the number in front of that element and the number of y will become the charge of that element and it's in an aqueous solution and then it's the same thing for n just the opposite direction the opposite way so um the number for y here will be the number in front of n right there and then the charge will be the x and the minus anyway um so then the ksp as you can see here we just have the m to the y plus and x is the value um that it's i guess to the power of and y is the value that is to the power of here as well and so if we consider that and look at these equations it becomes pretty easy to figure it out.

All i have to say is calcium 2 plus there, and chromate 2 minus.
01:43
There.
01:44
And that's the expression for the ksp right there.
01:48
And moving on to the second one, silver cyanide.
01:55
This is the expression, the chemical equation...
