Question

AgNO3 to solutions of each and determined the moles of AgCl precipitated. He also measured and

compared the conductances of solutions of each of these compounds with solutions of simple
electrolytes. Which response below gives all true statements concerning his conclusions from these
experiments?
I. From the moles of AgCl, he determined the total number of Cl ions in each
compound.
II. From the moles of AgCl, he determined the number of uncoordinated Cl ions in each
compound.
III. From the conductance of each solution, he determined the total number of ions present
upon dissolution of each compound.
a. I
b. II
c. III
d. I and II
e. II and III

Answer 1

d. I and II

Step-by-step explanation:

In chemistry, it is an old analytical technique to determine the amount of free chloride ions by silver chloride precipitation. This precipitation method could both be used to determine the initial chloride ion concentration in different analyte solutions or to determine the number of uncoordinated chloride ions in a complex. The number of moles of chloride ions in the silver chloride, shows the number of uncoordinated ions in a chloride ion containing complex.

The concentration of chloride ions in an analyte could be gravimetrically determined by silver chloride precipitation.
