which substances are acids? check all that apply. agoh hf niooh nh4oh hmno4 zn(oh)2
Answer
Explanation:
Step1: Recall acid - base definitions
Acids are substances that can donate a proton ($H^+$) in solution. Compounds with a hydrogen atom bonded to a non - metal or polyatomic anion and can dissociate to release $H^+$ are often acids.
Step2: Analyze each compound
- $AgOH$: It dissociates to $Ag^+$ and $OH^-$, it is a base.
- $HF$: In solution, it can dissociate into $H^+$ and $F^-$, so it is an acid.
- $NiOOH$: It is a basic compound as it contains the $OH$ group and can release $OH^-$ in solution.
- $NH_4OH$: It dissociates to $NH_4^+$ and $OH^-$, it is a base.
- $HMnO_4$: It can dissociate to release $H^+$ and $MnO_4^-$, it is an acid.
- $Zn(OH)_2$: It is a base as it can release $OH^-$ in solution.
Answer:
HF, $HMnO_4$
