A student is given 0.716 g of an unknown acid, which can be either oxalic acid, H2C2O4, or citric acid, H3C6H5O7. To determine which acid she has, she titrates the unknown acid with 0.430 M NaOH. The equivalence point is reached when 37.0 mL are added. Answer the following questions to determine the identity of the unknown acid. -How many moles of NaOH are consumed? Moles of NaOH = ____ mol -How many moles of H+ acid are available to react if the acid is H2C2O4? 0.0403 mol NaOH Moles of H+ from H2C2O4 = ___ mol -How many moles of H+ are available to react if the acid is H3C6H5O7? 0.0403 mol NaOH 0.0573 mol H+ from H2C2O4 Moles of H+ from H3C6H5O7 = ___ mo
