Earl N. Meyer found that it took 25.46mL of the 0.0100 M NaOH to reach the firtst equivalence point for the titration of 25.00mL of Zlot cola. What is the molar concentration of phosphoric acid in Zlot cola?

Answer 1

H3PO4 + NaOH ==> NaH2PO4 + H2O
moles NaOH = M x L = ??
moles H3PO4 = 1:1; therefore, = same as moles NaOH.
M H3PO4 = moles H3PO4/L H3PO4.
