Hi there.
00:04
For each of these compounds, we want to determine using the solubility rules if they are considered soluble or insoluble in water.
00:14
So the first one we come to is calcium hydroxide.
00:19
And we find that the only hydroxides that are considered soluble are the ones made with a group 1a salt or a group 1a metal in salt.
00:31
And calcium is not a group 1a metal.
00:33
And then also, of strontium and barium hydroxide are considered soluble.
00:39
All of the other hydroxides, which would include this one, are considered insoluble.
00:45
So our first one here is going to be insoluble.
00:51
Of course, remember, insoluble means it will not dissolve appreciably in water.
01:00
All right.
01:00
Our next one is magnesium sulfate in g -s.
01:04
S .o -4.
01:07
Looking at the solubility rules, we see that most sulfates are soluble.
01:12
There are a few exceptions.
01:13
Subceptions, sulfates that are prepared with silver, lead, mercury, calcium, strontium, or barium...
