                    why is it important to shield your silver chloride salt from light?                 

                    2-Determine the standard devlation of the following four measurements :24.76,25.83,24.35,and 25.26?                 

                    3-in the gravimetric analysis of a certain unknown containing chloride ,0.35g of unknown were used end 0.89 g of AgCl (s) were obtained after drying .what was                     the percent chloride in the original unknown?
                

Explanation / Answer

1) Photodecomposition is any photochemical reaction that results in the decomposition of a substance.Therefore, if silver chloride undergoes extensive photodecomposition, weighing it will produce low results.

2) mean = (24.76+25.83+24.35+ 25.26)/4 =25.05
