Question

part g provide the name of the oxyanion of the acid: h₃po₄(aq) spell out the full name of the ion.

Explanation:

Step1: Identify the acid and its dissociation

The acid given is $H_3PO_4$ (phosphoric acid). When it dissociates in water, it loses $H^+$ ions to form the oxyanion. The formula for the oxyanion is $PO_4^{3 - }$.

Step2: Name the oxyanion

The oxyanion $PO_4^{3 - }$ is named phosphate. This is based on the naming rules for oxyanions, where for the acid $H_3PO_4$ (phosphoric acid), the corresponding oxyanion is phosphate.

Answer:

phosphate
