Explanation:

Strong electrolytes are those that completely dissociate in water, so they exist mostly in the ionic form.

AB(aq) ⇒ A⁺(aq) + B⁻(aq)

On the other hand, weak electrolytes dissociate only partially in water, so that at equilibrium there is a mixture of the molecular form and the ionic form.

AB(aq) ⇄ A⁺(aq) + B⁻(aq)

Electrolytes can be acid or basic.

There are 7 strong acids: HCl, HBr, HI, HClO₃, HClO₄, HNO₃ and H₂SO₄. The rest of the acids are weak.

Strong bases are those hydroxides that contain cation from Groups 1 and 2 of the Periodic Table (e.g. NaOH, Ca(OH)₂). The rest of the bases are weak.

NH₃ , (CH₃)₂NH, and CH₃NH₂ are bases, despite not having OH⁻ groups, because they can accept H⁺, according to Bronsted-Lowry acid-base definition.

NH₃ + H₂O ⇄ NH₄⁺ + OH⁻

(CH₃)₂NH + H₂O ⇄ (CH₃)₂NH₂⁺ + OH⁻

CH₃NH₂ + H₂O ⇄ CH₃NH₃⁺ + OH⁻

With this information, we can classify the compounds from the list as a strong acid, strong base, weak acid, or weak base.
