Chemistry Procedure Part A Place 25mL of solution into clean beakers Measure the pH level of each solution with a pH meter o Rinse in-between each measurement Record data Measure the pH of these solutions using pH paper. Record data Consult pH scale of pg. 173 to determine molarity of each solution Part B Place 25ml of each solution into clean beakers Measure the pH level using pH meter Record data Part C -Don’t use pH meter for these tests If a solid, dissolve 0.1g of water in about 2mL of deionized water. If a liquid, place 10 drops in a clean beaker Use a clean stirring rod, obtain droplet of each solution and touch to the pH paper Record identity of material Part D Pipet 25mL of 0.1 M sodium acetate, NaC2H3O2 into a clean beaker Pipet 25ml of 0.1 M acetic acid HC2H3O2 into the same beaker o Mix completely o This is the buffer solution Measure pH of this solution, it is the buffer Record data
