question
according to the bronsted - lowry definition, what acts as the acid when the reaction below proceeds in the forward direction?
cn^- + h_2o ⇔ oh^- + hcn
select the correct answer below:
h_2o
hcn
oh^-
cn^-

Explanation:

According to the Bronsted - Lowry definition, an acid is a proton (\(H^+\)) donor. In the reaction \(CN^-+H_2O
ightleftharpoons OH^- + HCN\), \(H_2O\) donates a proton (\(H^+\)) to \(CN^-\) to form \(HCN\). \(H_2O\) loses a proton (\(H^+\)) in the forward reaction.

Answer:

A. \(H_2O\)
