agoh
hf
niooh
nh₄oh
hmno₄
zn(oh)₂

Explanation:

Acids are substances that release H⁺ ions in aqueous solution, typically with H as the first element in their formula. Bases/ hydroxides release OH⁻ ions.

• AgOH: A hydroxide (base)
• HF: Releases H⁺ and F⁻, is an acid
• NiOOH: A hydroxide-based compound (base)
• NH₄OH: Ammonium hydroxide (base)
• HMnO₄: Releases H⁺ and MnO₄⁻, is an acid
• Zn(OH)₂: A hydroxide (base)

Answer:

B. HF
E. HMnO₄
