1 point
A solution is known to contain only one type of anion. Addition of Ca2+
ion to the solution had no apparent effect (all ions remained in solution),
but addition of Pb2+ ion resulted in a precipitate. Which anion is present?

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
