Transcript

00:01 To calculate the molar solubility and the gram solubility, first we will write down the reaction which is going to happen.

00:06 So here we have a silver arsenate molecule that is ag3 aso4, ag3 s .o4.

00:12 In this, it decomposes to give 3ag plus plus aso4 3 minus.

00:20 So this is a quesform.

00:22 This is a quest form and this is a solid.

00:25 Okay.

00:26 Now in this case, what happens over here? so since we let's suppose we have the solubility as s.

00:34 So this becomes what? it will become 3s and this becomes s.

00:39 So here it will imply that the solubility product ksp will be equal to 3s, the whole cube multiplied by s.

00:48 Right? so this becomes 27s raised to 4.

00:55 So the ksp value is given to us that is 1 into 10 to minus 22.

00:59 1 into 10.

01:00 Minus 22.

01:02 So from this, we can calculate the molar solubility, that means s value.

01:06 Molar solubility, that means s value, which will be equal to fourth root of, fourth under root of 1 into 10 to the power of minus 22 divided by 27.

01:22 Right? so this is covering everything.

01:26 It is like the whole one.

01:30 Here we have 27.

01:31 So once we do this, this comes out to be equal to...
