4. Alka-Seltzer contains sodium bicarbonate (NaHCO3) and citric acid 113 CH 07. When a tablet is...
I Need the pre-lab
Questions, please
An Alka-Seltzer tablet consists of NaHCOs (sodium bicarbonate), citric acid (H3C&HsO; citric acid is triprotic), aspirin and other inert ingredients. When dissolved in water, citric acid and NaHCO3 components react as follows: In the first part of the experiment, we will determine the mass of NaHCO in a tablet of Alka Seltzer. To do this, we will use a known mass of a powdered sample of Alka-Seltzer and determine the mass of CO2 gas...
According to the manufacturer, a tablet of Alka Seltzer contains 1940 mg of sodium bicarbonate. From this mass and the balanced chemical equation, what mass of CO2 should be formed (and lost when the flask is swirled)? Show your work
-The fizz produced when an alka seltzer tablet is dissolved in water is due to the reaction between sodium bicarbonate NaHCo3 and Citric acid C6H8O7. What volume, in Liters, of a 2.50-M NaHCO3 solution is needed to react completely with 0.025L of a 3.00-M C6H8O7 solution? The balanced eq is 3NaHCO3+C6H8O7=3CO2+3H2O+Na3C6
The fizz produced when an AlkaSeltzer® tablet is dissolved in water is due to the reaction between sodium bicarbonate, NaHCO3, and a triprotic organic acid, citric acid, H3C6H5O7. The products of this reaction are carbon dioxide gas, water, and sodium citrate. 3 NaHCO3 (aq) + H3C6H5O7 (aq)→ 3 CO2 (g) + 3 H2O(l) + Na3C6H5O7 (aq) In an experiment 1.00 g of sodium bicarbonate and 1.00 g of citric acid are allowed to react. A.Which of the five compounds in...
8. A student performs parts A and B of the experiment and attains an average percent yield from the Alka- Seltzer of 64.6%. Using this value and the following data perform the calculations for part B and complete the table below. Assume the pressure has not changed. As it states in the manual: You may apply the findings regarding percent-yield in Part A to Part B when calculating the moles of calcium carbonate Trial 2 Trial 1 Mass Antacid used...
Sodium bicarbonate reacts with hydrochloric acid in a gas-forming reaction to produce aqueous sodium chloride, water, and carbon dioxide gas: NaHCO3(s) + HCl(aq) → NaCl(aq) + H2O(l) + CO2(g) Determine the mass of CO2 gas produced when 8.67 g of NaHCO3 is added to a solution that contains 5.65 g of HCl. ___g?
A. When a 3.28 g sodium bicarbonate tablet was dissolved in vinegar, 0.68 g of CO2 was produced. Use the stoichiometry NaHCO3(aq) + HC2H3O2(aq) → CO2(g) + H2O(l) + NaC2H3O2(aq) to calculate the amount (moles) of NaHCO3 consumed. B. Assume all the NaHCO3 consumed originated from the tablet. Calculate the mass of NaHCO3 in the tablet. C. Based on your answer on B, calculate the mass percent on NaHCO3 contained in the tablet.
How could one determine the frequency factor for this experimental system? citric acid+sodium bicarbonate→water+carbon dioxide+sodium citrate
Upon heating, sodium bicarbonate decomposes into sodium carbonate, carbon dioxide, and water vapor according to the following chemical reaction: 2 NaHCO3 (s) →→ Na2CO3 (s) + CO2 (g) + H2O (g) If the initial mass of sodium bicarbonate is 4.859 g, how much sodium carbonate should be produced? a. 3.066 g b. 2.211 g c. 6.131 g d. 4.859 g
Sodium bicarbonate (NaHCO3) is called baking soda because when heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, doughnuts, and bread. Calculate the volume (in liters) of CO2 produced by heating 8.37 g of NaHCO3 at 180°C and 1.12 atm.
