WebHalides 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. Web1 Answer. Sorted by: 10. The solubilities of silver halides decreases down the periodic table: A g F : K s p = 205. A g C l: K s p = 1.8 × 10 − 10. A g B r: K s p = 5.2 × 10 − 13. A g I : K s p = …

Webreactions. These reactions can occur by a range of mechanisms. SN2 and SN1 are the extremes. The SN2 reaction occurs in a single step. The nucleophile enters as the leaving group — usually a halide ion — departs. The reaction displays second-order kinetics; its rate is proportional to the concentration of the organo-halide and the nucleophile.
