A strong base in a water solution

• is a weak electrolyte

• produces many H⁺ ions

• will not dissolve

• completely dissociates into ions.

Which of the following statements is correct about the weak base, ammonia (NH₃)?

• It dissociates completely in water to produce a high concentration of hydroxide ions.

• It dissociates partially in water to produce a low concentration of hydrogen ions.

• It dissociates partially in water to produce a high concentration of hydroxide ions.

• It dissociates partially in water to produce a low concentration of hydroxide ions.

There are 2 types of acids and bases
