Answer

Brief Explanations:

An Arrhenius acid is a substance that dissociates in water to produce hydrogen ions ($H^+$). $HC_2H_3O_2$ (acetic - acid) dissociates in water as $HC_2H_3O_2\rightleftharpoons H^++C_2H_3O_2^-$ and $H_3PO_4$ (phosphoric acid) dissociates in water to release $H^+$ ions. $CH_3CH_2OH$ is an alcohol and does not dissociate to produce $H^+$ in the sense of an Arrhenius acid. $KHCO_3$ and $KHSO_4$ are salts. $NaSCN$ and $Na_2S_2O$ are also salts.

Answer:

B. $HC_2H_3O_2$ and $H_3PO_4$
