Explanation:
To calculate [H3O+] in the solution we must first find the pH from the [ OH-]
That's
pH + pOH = 14
pH = 14 - pOH
To calculate the pOH we use the formula
pOH = - log [OH-]
And [OH-] = 5.5 × 10^-5 M
So we have
pOH = - log 5.5 × 10^ - 5
pOH = 4.26
Since we've found the pOH we can now find the pH
That's
pH = 14 - 4.26
pH = 9.74
Now we can find the concentration of H3O+ in the solution using the formula
pH = - log H3O+
9.74 = - log H3O+
Find the antilog of both sides
<h2> H3O+ = 1.8 × 10^ - 10 M</h2>
The solution is basic since it's pH lies in the basic region.

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 = 
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
