In a neutralization reaction, an acid reacts with a base to produce a salt and water. This specific reaction involves hydrochloric acid [tex]\((HCl)\)[/tex] and cesium hydroxide [tex]\((CsOH)\)[/tex].
1. Dissociation of Hydrochloric Acid:
- Hydrochloric acid [tex]\((HCl)\)[/tex] dissociates in water to form hydrogen ions [tex]\((H^+)\)[/tex] and chloride ions [tex]\((Cl^-)\)[/tex]:
[tex]\[
HCl \rightarrow H^+ + Cl^-
\][/tex]
2. Dissociation of Cesium Hydroxide:
- Cesium hydroxide [tex]\((CsOH)\)[/tex] dissociates in water to form cesium ions [tex]\((Cs^+)\)[/tex] and hydroxide ions [tex]\((OH^-)\)[/tex]:
[tex]\[
CsOH \rightarrow Cs^+ + OH^-
\][/tex]
3. Neutralization Reaction:
- During the neutralization reaction, the hydrogen ions [tex]\((H^+)\)[/tex] from the acid combine with the hydroxide ions [tex]\((OH^-)\)[/tex] from the base to form water:
[tex]\[
H^+ + OH^- \rightarrow H_2O
\][/tex]
4. Formation of Salt:
- The remaining ions, which are the chloride ions [tex]\((Cl^-)\)[/tex] from the acid and the cesium ions [tex]\((Cs^+)\)[/tex] from the base, combine to form the salt cesium chloride [tex]\((CsCl)\)[/tex]:
[tex]\[
Cs^+ + Cl^- \rightarrow CsCl
\][/tex]
So, the ions that will combine to form the salt are:
- Chloride ion [tex]\((Cl^-)\)[/tex]
- Cesium ion [tex]\((Cs^+)\)[/tex]
Therefore, the correct ions that combine to form a salt in this neutralization reaction are:
- [tex]\(\mathbf{Cl^-}\)[/tex]
- [tex]\(\mathbf{Cs^+}\)[/tex]
These are the ions you should check as the combined ions for the formation of the salt.
