A solution is found to be 0.0942% by weight CoCl3. What is the concentration of the Cl1- ion expressed in ppm?
0.0942% by weight menas 0.0942 g in 100 g of solution.
Concentration of Cl^-1 ion is equal to 3 times that of CoCl3 solution.
Concentration of CoCl3 in ppm = (mass of solute/mass of solution)*10^6
= (0.0942/100)*10^6
= 942 ppm
Concentration of Cl^-1 ion in ppm = 3*942 ppm
= 2826 ppm
