Question

which of these compounds is likely to be sour and have a ph less than 7? lioh hcio al(oh)₃ nh₃

Explanation:

Step1: Recall acid-base properties

Acids are sour, have pH < 7, and release \(H^+\) ions. Bases are bitter, have pH > 7, and release \(OH^-\) or accept \(H^+\).

Step2: Analyze each compound

• \(LiOH\): Contains \(OH^-\), is a base (pH > 7), not sour.
• \(HClO\): Hypochlorous acid, releases \(H^+\), is an acid (sour, pH < 7).
• \(Al(OH)_3\): Hydroxide, acts as a base (pH > 7), not sour.
• \(NH_3\): Ammonia, a base (accepts \(H^+\), pH > 7), not sour.

Answer:

B. HClO
