According to general solubility rules, which type of compound is least likely to dissolve in water?
A
Ammonium acetate (NH4C2H3O2)
B

C
Silver chloride (AgCl)
D
Potassium sulfate (K2SO4)
Verified step by step guidance
1
Recall the general solubility rules for ionic compounds in water, which help predict whether a compound will dissolve or remain mostly insoluble.
Identify that compounds containing ammonium (NH4+) and alkali metal ions (like Na+ and K+) are generally soluble in water.
Recognize that most nitrate (NO3-) and acetate (C2H3O2-) salts are also soluble in water.
Note that silver chloride (AgCl) is an example of a halide salt that is generally insoluble or sparingly soluble in water due to the low solubility of many silver halides.
Conclude that among the given options, silver chloride (AgCl) is least likely to dissolve in water based on these solubility rules.
