Which of the following compounds is insoluble in water?
A
NH_4Br
B
AgCl

NaNO_3
D
K_2SO_4
Verified step by step guidance

Recall the general solubility rules for ionic compounds in water, which help predict whether a compound will dissolve or not.
According to solubility rules, most ammonium (NH_4^+) salts, such as NH_4Br, are soluble in water.
Nitrates (NO_3^-) like NaNO_3 are also generally soluble in water without exceptions.
Most potassium (K^+) salts, including K_2SO_4, are soluble in water as well.
Silver chloride (AgCl) is a classic example of a compound that is insoluble or only sparingly soluble in water, making it the correct choice for the insoluble compound.
