2.4  ×    10⁻² is the pH of a solution

What is the short definition of pH?

  • The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
  • In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

Equation representing the i onization of Na₃PO₄ is as fallow

              Na₃PO₄          →                 PO₄³⁻    +  3Na⁺

Concentration of Na₃PO₄ = \frac{26.9 * \frac{1 mol}{164 g} }{1 L} = 0.164 M

Since 1 mol of Na₃PO₄ forms 1 mol of  PO₄³⁻  [  PO₄³⁻  ] = [ Na₃PO₄ ] = 0.164 M

Equation representing the  i onization of HPO²⁻₄ is as fallow

 HPO²⁻₄          →         PO₄³⁻  +    H⁺

Acidionization constant Ka₃ of   HPO²⁻₄  = 4. 17 ×  10⁻¹³

Baseionization constant  Kb₃ of  PO₄³⁻ = Ka₃/ Kb₃

                              = 1 .0  ×  10⁻¹⁴/  4. 17 ×  10⁻¹³  = 2.4  ×    10⁻²

Answer:

This is not a redox reaction. None of the species are reduced and none are oxidized

Explanation:

In a redox reaction at least one species must be oxidized and another reduced. You see this by a change in oxidation number. In this question the oxidation numbers are the same before and after the reaction.
