Question

A 1-gram sample or a compound is added to 100 grams of H2O(l) and the resulting mixture is then thoroughly stirred. Some of the compound is then separated from the mixture by filtration. Based on Table F, the compound could be

(1) AgCl (3) NaCl

(2) CaCl2 (4) NiCl2

Answer 1

The answer is AgCl or Silver Chloride. Silver chloride is a biological compound with the chemical formula of AgCl. This white crystal-like rock-solid is well recognized for its little solubility in water. Upon light or heating, silver chloride transforms to silver (and chlorine), which is gestured by greyish or purplish coloring to other samples.
