Precipitation of Insoluble Metal Hydroxides from aqueous solutions containing salts using common alkalis such as NaOH & NH4OH Metal Ions in Solution + Alkali –> Insoluble Metal Hydroxide (PRECIPITATES) sean i don’t understand this reaction.can u please explain!!

In 2b: the products are Calcium Chloride and Water and, in 2c: the products are Calcium Chloride, Water and Ammonia Gas.
