Which one of the following represents the molecular equation for the reaction of HNO3 with CsOH?
A
H+(aq) + OH−(aq) → H2O(l)
B
HNO3(aq) + CsOH(aq) → Cs+(aq) + NO3−(aq) + H2O(l)
C
NO3−(aq) + Cs+(aq) → CsNO3(aq)
D
HNO3(aq) + CsOH(aq) → CsNO3(aq) + H2O(l)
Verified step by step guidance1
Identify the reactants: HNO3 (nitric acid) is a strong acid and CsOH (cesium hydroxide) is a strong base.
Recognize that the reaction between a strong acid and a strong base is a neutralization reaction, which produces water and a salt.
Write the general form of the neutralization reaction: acid + base → salt + water.
Write the molecular equation by combining the acid and base to form the salt (CsNO3) and water: \(\text{HNO}_3(aq) + \text{CsOH}(aq) \rightarrow \text{CsNO}_3(aq) + \text{H}_2\text{O}(l)\).
Confirm that this molecular equation correctly represents the reaction, showing the acid and base as intact molecules and the products as the salt and water.
