Equilibrium:The solution of NaOH was partly neutralized by

Equilibrium:

The solution of NaOH was partly neutralized by

H3PO4. The solution reached an equilibrium state of the mixture of NaOH, NaH2PO4, Na2HPO4and Na3PO4. The solution was left in the lab and some amount of water evaporated. Select the correct answer what will happen with the equilibrium concentrations of the chemical compounds. (The temperature remained the same. All chemical transitions NaOH→ NaH2PO4→ Na2HPO4→ Na3PO4 are exergonic.)

Concentrations of all compounds will increase proportionally;

Concentration of Na3PO4 will become relatively higher compared to other compounds;

Concentration of NaH2PO4 will become relatively higher compared to other compounds;

Concentration of NaOH will become relatively higher compared to other compounds;
