Answer to Question #323070 in General Chemistry for soph

Question

Find the concentration of all ions present in a 0.223 M solution of PbCl2. (2 marks for solvation, 2 marks for each concentration). 

Answer 1

Since that means that we have 0.223 moles of PbCl2 in 1000mL of solution.

Also since mole ratio of the ions Pb2+:Cl- is 1:2

Thus, moles of Pb2+ = 0.223moles

concentration of Pb2+= 0.223M

Moles of Cl- = 2x0.223 moles

Concentration of Cl- = 0.446M
