Which of the following chlorides is insoluble in water?
Answer Details
Among the given options, AgCl is the only chloride that is insoluble in water. This is because AgCl has a very low solubility in water, which means that only a small amount of it can dissolve in water. In contrast, KCl, NH4Cl, and ZnCl2 are all soluble in water, meaning they can easily dissolve in water to form a homogeneous solution. The solubility of a salt in water depends on various factors such as the nature of the ions, temperature, and pressure.
