Final answer:
The correct equation for the dissolution of CH₃NH₃Cl in water is CH₃NH₃Cl + H₂O → CH₃NH₃⁺ + OH⁻.
Step-by-step explanation:
The correct equation for the dissolution of CH₃NH₃Cl in water is option C) CH₃NH₃Cl + H₂O → CH₃NH₃⁺ + OH⁻. CH₃NH₃Cl is a salt, and when it dissolves in water, it dissociates into its component ions, forming CH₃NH₃⁺ (the conjugate acid) and OH⁻ (the hydroxide ion). This is an example of a neutralization reaction, where an acid reacts with a base to form a salt and water. The reaction can be represented as:
CH₃NH₃Cl + H₂O → CH₃NH₃⁺ + OH⁻
