hno₃(aq) ba(oh)₂(aq) nh₃(aq) hf(aq) hbr(aq)

Explanation:

• \(HNO_{3}(aq)\): Nitric acid is a strong acid as it completely dissociates in water (\(HNO_{3}

ightarrow H^{+}+NO_{3}^{-}\)).

• \(Ba(OH)_{2}(aq)\): Barium hydroxide is a strong base. It dissociates completely in water (\(Ba(OH)_{2}

ightarrow Ba^{2 +}+2OH^{-}\)).

• \(NH_{3}(aq)\): Ammonia is a weak base. In water, it undergoes partial dissociation (\(NH_{3}+H_{2}O

ightleftharpoons NH_{4}^{+}+OH^{-}\)).

• \(HF(aq)\): Hydrofluoric acid is a weak acid. It only partially dissociates in water (\(HF

ightleftharpoons H^{+}+F^{-}\)).

• \(HBr(aq)\): Hydrobromic acid is a strong acid. It completely dissociates in water (\(HBr

ightarrow H^{+}+Br^{-}\)).

Answer:

• \(HNO_{3}(aq)\): Strong acid
• \(Ba(OH)_{2}(aq)\): Strong base
• \(NH_{3}(aq)\): Weak base
• \(HF(aq)\): Weak acid
• \(HBr(aq)\): Strong acid
