Hi, in this question we are asked to list sulfates of group 2a metals and we are also asked to arrange them in increasing solubility in water.
00:10
First of all we will write the sulfates in group 2a we are having sulfates such as b -e -e -sophore beryllium sulfate, mg -g -sof -4 magnesium sulfate, c .a.
00:27
So4, calcium sulfate, s .r.
00:31
S .o .4, strontium sulfate and vaso4, barium sulfate.
00:37
Now, in order to make a relation with the solubility, we can say that hydration energy is directly proportional to solubility.
00:53
And if we talk about the hydration energy, let's say h .e.
00:59
Is inversely proportional to radius of ketion.

Here, in these sulfates, there is difference in cations only, since all sulfate are containing so4 -2 -minus, which is same in all...
