A: Explain the relationship between the rate of a chemical reaction and experimental parameters. Unit 8: Acids and Bases Topic 8. C: Explain the relationship among pH, pOH, and concentrations of all species in a solution of a monoprotic weak acid or weak base.
Topic 8. A: Explain the relationship between the predominant form of a weak acid or base in solution at a given pH and the pKa of the conjugate acid or the pKb of the conjugate base.
Objectives By the end of this demonstration, students should be able to Understand that a chemical change is taking place. Recognize that an indicator causes the color change. Realize that an acid base reaction is taking place. Recognize the limiting and excess reactants during the reaction. Safety Always wear safety goggles when handling chemicals in the lab. Students should wear proper safety gear during chemistry demonstrations.
Safety goggles and lab apron are required. Students should wash their hands thoroughly before leaving the lab.
Milk of Magnesia MOM is a common antacid. You can choose any antacid that is primarily magnesium hydroxide Mg OH 2. MOM is a magnesium hydroxide suspension. It is composed of many different compounds that change color at specific pH values. The density is 1.
When vinegar is added the solution will briefly turn red, and then change to orange, yellow, green, and back to blue as the vinegar reacts with the magnesium hydroxide. The vinegar will be the limiting reactant for the first several additions. As the magnesium hydroxide reacts with each addition of vinegar, the pH reached when equilibrium is reestablished will be slightly lower.
Once all of the magnesium hydroxide has reacted and excess vinegar is added, the solution will stay red because of the acetic acid that is present in the solution. The acid-base neutralization reaction between the magnesium hydroxide and acetic acid progresses until one runs out vinegar in all but the last addition.
