Solution: Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients. A precipitate forms when aqueous solutions of calcium chloride

Problem

Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients. A precipitate forms when aqueous solutions of calcium chloride and cobalt(II) sulfate are combined. Do not include states such as (s) or (aq). It is not necessary for you to indicate which of the products is the precipitate.


Solution

Calcium chloride and cobalt (II) sulfate will appear as CaCl2 and CoSO4

Double-replacement/displacement reaction means that we are just switching the cations and anions for the product

Balanced reaction will appear as:
