1. On the box of Arm and Hammer baking soda it says the contents are sodium bicarbonate. Basically this means the contents are pure sodium bicarbonate. The box also says that baking soda can be used as an antacid and says that 1 dose is 1/2 level teaspoon in 4 fl oz. of water. Write a chemical equation for the reaction of hydrochloric acid with baking soda that takes place in the stomach. Show the physical states of the reactants and products.
2. Write the total ionic and net ionic equations for this reaction.
3. What is the neutralizing power of baking soda in terms of moles of HCl neutralized per gram of baking soda.
4. What is the neutralizing power of one dose of baking soda? One dose is 1/2 teaspoon of baking soda dissolved in 4fl oz of water.Use 0.71 g/mL as the density of granular baking soda. 1teaspoon = 4.93 mL
5. How many milligrams of sodium chloride is formed in the stomach from one dose of baking soda?
6. Most dietry experts recommend limiting the amount if sodium ions in the diet. Assume a person wished to eat no more than 2400 mg of sodium per day. What percentage of that amount would one dose of baking soda represent?
7. Which is cheaper per mole of hydrochloric acid neuralized, a generic antacid that costs $8.99 for a bottle of 500 tablets each of which contains 1000 mg of CaCO3 or a 1 pound box of baking soda that costs $0.69 per box?
