Data and Calculations for Sodium Carbonate (the Excess Reagent) Based on the amount of potassium bitartrate you started with (from line 1 on page 164), how many grams of sodium carbonate were needed to react with it! Show your calculation as in Example 3. 3.111g KH5640₂x Imol KHS 4 Ou Imol Naz 60 *2mol KNOCY Du 188.18g KHS640u 7. Calculated mass of sodium carbonate, Na,CO,. needed 8. Mass of weigh boat and Na,CO, (before reaction) 9. Mass of weigh boat and Na,CO, (after reaction) Preparation of Rochelle Salt... 10. Mass of Na₂CO, used 3.034 2.054 Compare how much sodium carbonate you actually used to the amount you needed. (Lines 7 and 10) Did you use close to the calculated amount! If you used excess sodium carbonate, do you think the excess is mixed in with the crystals you isolated? If not, what do you think happened to the excess sodium carbonate? REPORT SHE
