How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?

Select all that apply. using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 (s) pb+2(aq) + 2cl -(aq). the concentration of the products yield a ksp of 2.1 x 10-2:
