Lab Report: Acid and Base Indicator Lab
The title of my lab report is “Acid and Base Indicator Lab” this lab is testing what household solutions area bases depending on what color they changed. You have to use the pH balance scale to determine Acid, Base, and Neutral.
On this lab we used 7 different solutions to determine if it’s either base, acid, and neutral. These are ammonia, vinegar; drain cleaner, soft drink, baking soda, detergent, and lemon juice are the solutions that are going to be tested in this lab. My hypothesis for these solutions is ammonia is acid, vinegar is neutral, drain cleaner is base, soft drink is base, baking soda is base, detergent is base, and lemon juice is an acid. For the red cabbage it would be the same as using red and blue litmus. If the pH number of the solutions is less than 7 then lemon juice is the only that is acid but it’s weak. If the pH number of the solutions is greater than 7 then ammonia, drain cleaner, soft drink, baking soda, and detergent are bases. If a solution equals 7 then vinegar is neutral.
Some of the materials are red litmus paper, blue litmus paper, hydrion paper, pipets, and 12 well spot plates. The other materials that are chemicals or solutions are red cabbage juice, drain cleaner (NaOH), detergent, baking soda (NaHCO3), ammonia (NH3), soft drink, distilled water, vinegar (CH3CO2H), and lemon juice.
For Part A the first step is on a paper towel lay-out seven pieces of red litmus paper, seven pieces of blue litmus paper, and seven pieces of hydrion paper. Second step is use the pipet place one drop of the first solution on the red litmus paper and record observations. Third step is use the pipet place one drop of the first solution on the blue litmus paper and record observations. The fourth and last step is repeat steps 2-4 with the remaining solutions. For Part B the first step is on a sheet of paper draw a diagram of a spot plate and decide which well will be used for each solution, then place...
