Concept explainers
Predict whether each of the following reactions will occur in aqueous solutions. If you predict that a reaction will not occur, explain your reasoning. Note: Barium sulfate and silver bromide precipitate in aqueous solutions.
(a)
Interpretation:
Whether the given reaction takes place in aqueous solution or not needs to be determined.
Concept introduction:
In a chemical reaction, atoms of substances rearrange to form a new substance.
Answer to Problem 110A
The given reaction does not occur in aqueous solution.
Explanation of Solution
If a gas, water or a solid is produced a double displacement reaction will occur. Given reaction is double displacement reaction. Sodium is most reactive metal in the activity series. It reacts with water. To predict if the given reaction will occur in aqueous solutions, switch the cations from the reaction and look up the state of the products. The given reaction is as follows:
(b)
Interpretation:
Whether the given reaction takes place in aqueous solution or not needs to be determined.
Concept introduction:
In a chemical reaction, atoms of substances rearrange to form a new substance.
Answer to Problem 110A
This reaction will occur in aqueous solution.
Explanation of Solution
The given reaction is as follows:
In this reaction precipitate forms product thus, this reaction will occur in aqueous solution.
(c)
Interpretation:
Whether the given reaction will occur in aqueous solutions or not needs to be determined.
Concept introduction:
In a chemical reaction, atoms of substances rearrange to form a new substance.
Answer to Problem 110A
This reaction will occur in aqueous solution.
Explanation of Solution
If a gas, water or a solid is produced a double displacement reaction will occur. The given reaction is as follows:
In this reaction precipitate forms product thus, this reaction will occur in aqueous solution.
