Question

question 4 of 10
which of the following is an example of a bronsted - lowry base?
a. $nh_{4}^{+}$
b. $h_{3}o^{+}$
c. $nh_{3}$
d. $hcl$

Explanation:

A Brønsted - Lowry base is a substance that can accept a proton (\(H^{+}\)).

• \(NH_{4}^{+}\) (Option A) is a Brønsted - Lowry acid as it can donate a proton.
• \(H_{3}O^{+}\) (Option B) is a Brønsted - Lowry acid as it can donate a proton.
• \(NH_{3}\) (Option C) can accept a proton (\(NH_{3}+H^{+}\to NH_{4}^{+}\)), so it is a Brønsted - Lowry base.
• \(HCl\) (Option D) is a Brønsted - Lowry acid as it can donate a proton (\(HCl = H^{+}+Cl^{-}\)).

Answer:

C. \(NH_{3}\)
