Two different ionic compounds each contain only copper and chlorine. Both compounds are powders, one white and one brown. An ele
mental analysis is performed on each powder. Which of the following questions about the compounds is most likely to be answered by the results of the analysis? A. What is the density of each pure compound?
B. What is the formula unit of each compound?
C. What is the chemical reactivity of each compound?
D. Which of the two compounds is more soluble in water?
Elemental analysis involves the actual percentage compositions of each element in the sample of the compounds. We know that there are two different compounds here that both contain copper and oxygen. What we don't know is the actual number of copper or oxygen composed in the compounds.
An elemental composition of these compounds would thus tell us this and will give an idea of the chemical formula of each since we now know quite well the percentage composition of each of these elements
