Question #13355
1 Answer
Although there are exceptions, the general trend is that solubility increases from top to bottom of Group 1 and from top to bottom of Group 17.
Explanation:
Here are the solubilities of the Group 1 halides in grams per 100 mL of water at 20 °C.
The two major exceptions for individual solubilities are marked in
Note also that the solubility trend for fluorides is the opposite of the trends for chlorides and bromides.
