which of the following substances is an arrhenius acid?\n○ bf₃\n○ hcn\n○ nh₃\n○ mg(oh)₂
Answer
Brief Explanations:
An Arrhenius acid is a substance that dissociates in water to produce hydrogen ions ($H^+$). $BF_3$ is a Lewis - acid, $NH_3$ is a base that accepts a proton, and $Mg(OH)_2$ is a base that dissociates to give hydroxide ions ($OH^-$). $HCN$ dissociates in water as $HCN\rightleftharpoons H^++CN^-$, releasing hydrogen ions.
Answer:
HCN
