# Which silver halide is the most soluble?

Halides are group 7 elements. They generally have a low melting and boiling point. They are highly reactive. Silver chloride and silver bromide are not soluble in water. So they will be precipitates. However, I do know that they have varying solubilities. So, they will form different amounts of precipitates. I want to know why they have different solubilities and which is the most soluble halide.

• $\ce{AgF}\ : K_{sp} = 205$
• $\ce{AgCl}: K_{sp} = 1.8\times10^{-10}$
• $\ce{AgBr}: K_{sp} =5.2\times10^{-13}$
• $\ce{AgI}\ \ \ : K_{sp} =8.3\times10^{-17}$
