Question

Determine whether each substance listed is a strong acid, weak acid, strong base, weak base, acid salt, basic salt, or neutral salt. a) sodium hydroxide, NaOH b) ammonium chloride, NH4Cl c) perchloric acid, HClO4 g

Answer 1

Answer:

a) Strong Base

b) Acid Salt

c) Strong Acid

Explanation:

• a) sodium hydroxide, NaOH

As is the case with most hydroxides, NaOH is a strong base. It dissociates completely into Na⁺ and OH⁻ species when in water.

• b) ammonium chloride, NH₄Cl

NH₄Cl is a acid salt, as it produces H⁺ species when dissolved in water:

• NH₄Cl → NH₄⁺ + Cl⁻

• NH₄⁺ → NH₃ + H⁺

• c) perchloric acid, HClO₄

HClO₄ is a strong acid, as it completely dissociates into H⁺ and ClO₄⁻ species when in water.
