Question

question 6 (5 points) in the following reaction, water behaves as ch3nh2 + h2o ⇌ ch3nh3+ + oh⁻ a) an acid b) a base c) a salt d) a conjugate base

Explanation:

In the reaction $\ce{CH3NH2 + H2O <=> CH3NH3+ + OH-}$, water donates a proton ($\ce{H+}$) to $\ce{CH3NH2}$. By the Bronsted - Lowry definition, an acid is a proton donor. So water acts as an acid here.

Answer:

a) an acid
