Which of the following compounds would be more soluble in 1 M NH3 than in pure water? BaSO 4 AgBr Pbl 2 BaF 2 Ca(OH) 2

AgBr

Explanation:

The salt, AgBr has a very low solubility is pure water. However, it has a high solubility in 1 M NH3. The reason behind this higher solubility of AgBr in 1 M aqueous ammonia solution is the formation of a complex as shown below;

AgBr(s) + 2NH3(aq) > [Ag(NH3)2]^+(aq) + Br^-(aq)

The formation of this linear silver diammine complex accounts for the higher solubility of AgBr in 1 M aqueous ammonia solution.

i would say b

explanation:

but i think i would need more information than that

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
