1) What is the solubility of PbI2 in g/l, if the solubility product is 7.9x10-9
2) Cu(s)/ Cu+2 (0.02M) //Zn2+ (0.02M)/Zn(s); the standard reduction potential for Cu and Zn is 0.34 and -0.76 respectively. Calculate the standard cell potential, change in free energy and cell potential
1.) Let the solubility of in 0.01M NaI solution be s M.
Then in this case,
Neglecting and terms, we get:
2.) In this part we can use the Nernst Equation,
