Question

chemistry: fundamentals and principles presented by macmillan learning davidson classify the compounds as a strong acid, weak acid, strong base, or weak base. strong acid weak acid strong base weak base hbr nh₃ answer bank

Explanation:

Step1: Recall acid - base definitions

Strong acids completely dissociate in water, weak acids partially dissociate. Strong bases completely dissociate to give hydroxide ions, and weak bases only partially react with water to produce hydroxide ions.

Step2: Analyze HBr

HBr is one of the seven common strong acids. In water, it completely dissociates as \(HBr(aq)
ightarrow H^{+}(aq)+Br^{-}(aq)\), so it is a strong acid.

Step3: Analyze NH₃

Ammonia (\(NH_{3}\)) is a weak base. It reacts with water in a reversible reaction \(NH_{3}(aq)+H_{2}O(l)
ightleftharpoons NH_{4}^{+}(aq) + OH^{-}(aq)\), only partially producing hydroxide ions.

Answer:

Strong acid: HBr
Weak acid: (No compound provided in this category from the given ones)
Strong base: (No compound provided in this category from the given ones)
Weak base: NH₃
