Problem- A group of students performed a titration experiment. They took 25.00mL of solution of phosphoric acid of unknown concentration, and then added dropwise the 0.125 M solution of sodium hydroxide. When 17.37 mL of sodium hydroxide solution was dispensed, the students observed that the base has completely neutralized the acid.

a) Write the balanced equation of a chemical reaction between sodium hydroxide ("base") and phosphoric acid ("acid"). Assume complete neutralization.

b) Calculate the molarity of phosphoric acid solution from given data.

I need expert help to solve the above question. Show each and every step.
