Experiment 8: Stoichiometry and Chemical Reactions Lab Report According to the demonstration video of the experiment, the following reaction of baking soda and hydrochloric acid is taking place: NaHCO3 + HCI > NaCl + CO2 + H20 1. What is the stoichiometric ratio of NaHCO,_: NaCl? (1 point) 2. What is the name of the acid-base indicator used for the experiment? (1 point) 3. What is the color of this indicator in acidic and in basic media? (1 point) 4. Why is an indicator used in the experiment? (1 point)

5. If 2.0 g of baking soda (NaHCO3) is reacted with HCI according to the reaction equation above. (molar mass of Na = 23 g/mol, H = 1 g/mol, C = 12 g/mol, O - 16 g/mol, Cl = 35.5 g/mol.) - (4 points) - Always show your calculations. a. Calculate the number of moles of 2.0 g of baking soda (NaHCO3). (2 points) b. What is the number of moles of NaCl that would be produced from the reaction. (2 points) c. Calculate the theoretical mass of NaCl in grams that should be produced from the reaction above. (2 points)

d. If what was experimentally produced in the lab was 1.03 g. What is the "/9 yield of the reaction? (2 points) Show your calculations for the questions below. 6. 0.5 M HCl has moles of HCl in 400 ml of solution. (1 point) T. m] of 10 M H2304 shall contain 5 moles of H2804. (1 point) 8. If 30 g. of NaOH were dissolved in water to form 1 liter of NaOH solution. What is the molarity of that solution? (3 points)
