2. How many mL of 0.100M NaOH would you need to titrate if you measured out 0.120 g of oxalic acid? Must show calculation. (5 pts) lying an unknown acid Objective: Identify an unknown diprotic acid by determining its molecular weight. Introduction: A diprotic acid is an acid that yields two H ions per acid molecule. Therefore, two moles of NaOH are need to react with every one mole of diprotic acid. The net reaction of a diprotic acid, H:X,...
