which statement best describes a bronsted - lowry base? it must accept protons to form a conjugate base. it must accept protons to form a conjugate acid. it must donate protons to form a conjugate base. it must donate protons to form a conjugate acid.
Answer
Answer:
It must accept protons to form a conjugate acid.
Brief Explanations:
According to the Brønsted - Lowry theory, a base is a proton - acceptor. When a base accepts a proton ($H^+$), it forms its conjugate acid. For example, in the reaction $NH_3 + H_2O\rightleftharpoons NH_4^++OH^-$, ammonia ($NH_3$) is a Brønsted - Lowry base as it accepts a proton from water to form the ammonium ion ($NH_4^+$), which is its conjugate acid.
