Which of the following best describes the outcome of mixing NaOH (aq) and CaBr2 (aq) based on solubility rules?
A
A precipitate of NaBr forms, and Ca(OH)2 remains in solution.
B
Both NaOH and CaBr2 remain in solution without any reaction.
C
No reaction occurs because all products are soluble.
D
A precipitate of Ca(OH)2 forms, and NaBr remains in solution.
Verified step by step guidance1
Identify the reactants in the mixture: NaOH (aq) and CaBr2 (aq).
Write the balanced chemical equation for the reaction: .
Apply solubility rules to determine the solubility of the products: NaBr is soluble in water, while Ca(OH)2 is insoluble and forms a precipitate.
Explain why Ca(OH)2 forms a precipitate: According to solubility rules, hydroxides of alkaline earth metals like calcium are generally insoluble in water.
Conclude that the correct outcome is the formation of a precipitate of Ca(OH)2, while NaBr remains dissolved in the solution.
