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 = 
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

What basically your question is can you tell
Answer:
Water and acetone is best by separated through distillation
The correct answer would be option C Acetone and water.
Explanation:
When in a mixture of fluid solution, two liquids are mixed in a form of mixture then these liquid can be separated only one method which is based on the fact. That two different liquids will have two different boiling temperatures which method of separating the Fluids is distillation.
The different liquids that are present in mixture are boiled and the vapours are condensed and the condensed portion is accumulated in another beaker.
Answer: 
Explanation: A double displacement reaction is one in which exchange of ions take place.
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
