After you have recorded and any other glassware you have used. All waste can go down the sink. the mass of the beaker after the reaction, you may rinse out the beaker 10. CALCULATIONS: a) Rewrite the balanced chemical equation here Calculate the theoretical amount of sodium acetate that should be formed in the reaction (follow steps 1-3 below). b)...
At high temperatures, sodium bicarbonate is converted quantitatively to sodium carbonate, producing water and carbon dioxide. Heating a 1.7184 g sample of impure NaHCO3 produces 0.196 grams of CO2. Determine the mass percent of sodium bicarbonate in the original mixture. (Assume the impurities do not decompose when heated.)
A 25.00 mL sample contains 0.562 grams of NaHCO3 (sodium bicarbonate a.k.a. baking soda). The sample is used to standardize a NaOH (sodium hydroxide) solution. At the equivalence point (determined by pH meter and phenolphthalein) 40.95 mL of NaOH has been added. What is the concentration of the NaOH solution? Report the solutions to 3 decimal places. Hint: NaHCO3 and NaOH react in a 1:1 stoichiometric ratio.

Sodium hydrogen carbonate (NaHCO₃), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCl), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO₃ neutralizes excess HCl through this reaction:HCl(a q)+NaHCO₃(a q) → NaCl(aq)+H₂ O(l)+CO₂(g)The CO₂ gas produced is what makes you burp after drinking the solution.Suppose the fluid in...
