Question

Although you did not test the bromide (Br-) anion, would you expect most bromide salts (AlBr3, NH4Br, BaBr2, etc.) to be soluble or insoluble? What is the likely exception to this rule? Hint: Use the periodic table to see which of the anions you tested would behave like bromide.

Answer 1

Based on the solubility guidelines, most bromide salts, such as AlBr3, NH4Br, and BaBr2, are expected to be soluble in water. The likely exception to this rule would be silver bromide (AgBr), which is insoluble in water.
