First we'll write the ksp reaction for silver chloride that is agcl solid dissociating into ag plus mcl minus ksp is equal to the silver concentration multiplied by the chloride concentration and they tell us that value.
00:27
Oh, they didn't give it to us.
00:29
So i'll have to look it up.
00:31
I don't have access to the alex data, but i do have access to ksp values.
00:36
So hopefully the value i have is very close to the one you have.

In my book, it's 1 .6 times 10 to the negative 10.
00:47
When one mole of the solid dissolves in a liter of solution, we get one mole of silver and one mole of chloride.
00:53
So the silver concentration and the chloride concentration will both be equal to each other.
00:58
And they'll both be equal to the moles of the solid that dissolve in a liter.
01:03
So replacing each of these with s gives us s squared is equal to 1 .6 times 10 to the negative 10.
01:12
So the molar solubility is simply 1 .6 times 10 to the negative 10, to which we've taken the square root, giving us s equal to 1 .26 times 10 to the negative 5, and that's moles of silver chloride per liter...
