Here in this problem, five compounds are given and we have to determine which of the following solid compound is insoluble in water.
00:12
Now, the first one is ammonium carbonate.
00:17
Now, salts containing group one elements and ammonium ion are soluble according to the solubility rule.
00:27
So, ammonium carbonate, this is soluble in water.
00:34
Then potassium chromate.
00:36
Any salt containing group 1 elements like potassium, sodium, rubidium, cygium, is soluble in water.
00:44
So potassium chromate k2cr4 is soluble in water.
00:51
Then barium sulphate.
00:54
Most of the sulphate salts are soluble with few exceptions.
00:59
And barium sulphate is one of that exceptions...
