1. Complete and balance the following equation:
H2X(aq) + OH-(aq) --» ? + ?
2. In an imaginary experiment, a student found that 0.113 g of solid acid required 18.76 mL of sodium hydroxide solution (0.102 M) to reach the end point. Determine the molar mass of this imaginary diprotic acid.

-
H2X + OH- --> H2O + X-.....conjugate base of the H2X acid
0.01876L x 0.102M = 1.92.x10^-3moles OH- used
acid = diprotic so 1.92x10^-3moles OH- neutralized 9.57x10^-4moles acid
0.113g / 9.57x10^-4moles = 118.11g/mole
