Question

in the following reaction,
ch₃nh₂ + h₂o→ch₃nh₃⁺ + oh⁻

an acid
a base
a salt
a conjugate acid
question 2
6 pts
the hydronium ion is responsible for the properties of
acids.
bases.
salts.

Explanation:

• For the first reaction \(CH_3NH_2 + H_2O

ightarrow CH_3NH_3^+ + OH^-\), according to the Bronsted - Lowry theory, a base is a substance that can accept a proton (\(H^+\)). Here, \(CH_3NH_2\) accepts a proton from \(H_2O\) to form \(CH_3NH_3^+\), so it acts as a base.

• For the second part, according to the Arrhenius and Bronsted - Lowry theories, acids are substances that produce hydronium ions (\(H_3O^+\)) in aqueous solution, and the properties of acids (such as sour taste, ability to turn blue litmus red, etc.) are due to the presence of hydronium ions.

Answer:

• First question: a base
• Second question: acids
