Question

How many types of ions must be present in solution, at minimum, for the phenomenon of selective precipitation to be observed? Your answer should be a whole number without any decimal places.

Answer 1

Two (2) types of ions

Step-by-step explanation:

Metal ions (cations) and negatively charged ions (anions) of either chloride, carbonate, sulphides or hydroxides are present during the selective precipitation.

Majorly, the process determines the metal ions present by initiating precipitation as certain conditions.
