A group of students performed a titration experiment. They took25.00mL 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, thestudents observed that the base has completely neutralized theacid.
a) Write the balanced equation of a chemical reaction betweensodium hydroxide ("base") and phosphoric acid ("acid"). Assumecomplete neutralization.
b) Calculate the molarity of phosphoric acid solution from givendata.
