Concept explainers
Interpretation: The following precipitation reaction should be balanced:
Concept Introduction: The reactions for those the number of atoms of each element in the reactant and in the product, side are equal, such reactions are said to be a balanced chemical equation.
Answer to Problem 12A
Explanation of Solution
The given precipitation reaction is:
The given reaction is not balanced as the number of atoms of Na and Cl on the reactant is 2 whereas on the product side is 1 for each, so, in order to balance the reaction, coefficient 2 is written before NaCl on the product side. Thus, the balanced reaction is:

Answer to Problem 12A
Explanation of Solution
The given precipitation reaction is:
The given reaction is not balanced as the number of atoms on reactant side is:
And on product side is:
So, in order to balance the reaction, coefficient 2 is written before

Answer to Problem 12A
Explanation of Solution
The given precipitation reaction is:
The given reaction is not balanced as the number of atoms on reactant side is:
And on product side is:
So, in order to balance the reaction, coefficient 2 is written before KOH on the reactant side and coefficient 2 is written before KCl on the product side. Thus, the balanced reaction is:
