Baking soda and calcium chloride (one type of de-icer) are mixed, and then phenolsulfonphthalein (phenol red) in solution is added. The water in which the phenol red is dissolved allows the other molecules to get close enough to react, but its atoms do not recombine. It is …

We used quantitative data to determine which of the four given equations best fit the thermal decomposition of baking soda. Our plan to conduct the chemical reaction was to begin with 2g of baking soda in a crucible, place it over a flame from a Bunsen burner for 5 minutes (until the chemical reaction was complete), then measure the mass of the resulting product.

12. Mass is conserved when the mass of reactants in a chemical change is the same as the mass of the products. This is true for all chemical reactions as long as nothing is added or lost. Students measure 2.0 g of baking soda and 5.0 g of vinegar. They mix them together in a . beaker and watch as bubbles form. The mass of the resulting liquid ...

Baking soda, NaHCO3, and milk of magnesia, which is an aqueous suspension of magnesium hydroxide, Mg(OH)2(s), are used as antacids. Both neutralize excess hydrochloric acid secreted by the stomach. (a) Write a balanced equation for the reaction: (i) between NaHCO3(s) and HCl(aq); (ii) between Mg(OH)2 and HCl(aq).

In this experiment, baking soda will react with hydrochloric acid to yield a salt, water and carbon dioxide gas. The HCl acid is in excess in the reaction so that the moles of CO2 gas produced may be determined from the moles of the NaHCO3 that react.
