Question

which of these terms describes ethylamine, ch3ch2nh2?
weak acid weak base
strong base strong acid

Explanation:

Ethylamine ($\ce{CH3CH2NH2}$) has an amino group ($\ce{-NH2}$). Amines act as bases because the nitrogen atom can accept a proton ($\ce{H+}$) to form $\ce{-NH3+}$. Ethylamine does not fully ionize in water, so it is a weak base (strong bases like $\ce{NaOH}$ ionize completely, while weak bases ionize partially). Acids donate protons, and ethylamine does not act as an acid here.

Answer:

weak base
