Question

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

Explanation:

Step1: Analyze the nature of each compound

• \(Al(OH)_3\) is a base. Bases have a pH greater than 7.
• \(NH_3\) (ammonia) forms a basic solution when dissolved in water (\(NH_3 + H_2O

ightleftharpoons NH_4^+ + OH^-\)), so it has a pH greater than 7.

• \(HClO\) (hypochlorous acid) is an acid. Acids have a sour taste and a pH less than 7 (\(HClO

ightleftharpoons H^+ + ClO^-\)).

• \(LiOH\) is a strong base (\(LiOH = Li^+ + OH^-\)). Bases have a pH greater than 7.

Answer:

C. \(HClO\)
