Identify Mystery Liquid - act ExampleHandle bouncy beakers using beaker tongs. 2. Wear protective gear gloves and overall. 3. be cautious succession handling dissolving agents such as drain cleaners since they are caustic. 4. Avoid eye and skin clear up with the chemicals. 5. Wash out any contact with the chemicals with large quantities of water. Procedure 1. Chop red fleece into humble pieces and place them in a 100-mL beaker and add 30 mL of distilled water. 2. Place the beaker on a hot plate, and allow the water to boil until a deep purple color appears. Using beaker tongs, carefully mutilate the hot beaker from the hot plate give it time to cool then transfer the red cabbage indicator to a clean beaker. 3. Place a clean microplate over a piece of snow-white paper. Using pipets add 5 drops of lemon juice to L1 drain cleaner to L2, and Anti-freezer to L3. For each solution map a clean pipet. 4. Draw the red cabbage indicator into a clean pipet, and to each solution L1-L3 add 5 drops of the red cabbage indicator. Stir the solutions carefully using a stirring rod. 5. By clearly observing the three solutions, saucer the color changes in the data table. With reference to the color chart, record the approximate PH of every solution. Acid & Base Observations Solution color Approximate PH proof Lemon Juice Light red 2 slightly acidic Drain Cleaner chicken 13-14 Basic Anti-freezer Green 10.5 basic Conclusion From the above observation it very clear that the liquid instal by Mr. Fischer was likely to be lemon juice and not drain cleaner or anti-freezer. commentary Drain cleaner was name to have a PH of 13-14 which depicted a basic solution. The anti-freezer was found to have a PH of 10.5 depicting a basic solution too. Lemon juice was the scarce liquid found to be acidic. Lemon juice Corresponded to the liquid found in such a way that its acidic nature would corrode metals. DOCUMENT B pH OF COMMON SUBSTANCES WITH THEIR IUPAC NAMES pH OF COMMON SUBSTAN CES pH H3O+, M Example 0 1.0 Battery acid, 1 M sulfuric acid 1 1 ? 10?2 Lemon juice 2-hydroxypropane-1,2,3-tricarboxylic acid 2 1 ? 10?3 acetum impure dilute acetic acid 3 1 ? 10?4 Soft drink sodium bicarbonate 4 1 ? 10?5 Rain water H2O 5 1 ? 10?6 Milk Lime atomic number 20 hydrated oxide 7 1 ? 10?8 Baking soda, sodium bicarbonate 8 1 ? 10?9 Washing soda, Na2CO3 sodium carbonate 9 1 ? 10?10 Anti-freezer ethylene glycol 10 1 ? 10?11 aqueous household ammonia, NH3 11 1 ? 10?12 Limewater, aqueous solution of calcium hydroxide Common household chemicals (Katz 2-4) DOCUMENT C A household hazardous waste that can be identical to the liquid found in the house must have acidic properties, meaning that it whitethorn corrode metal containers and turn red cabbage indicator juice red. Corrosive substances can cancel out into skin and metal therefore they need to be handled with care and disposed correctly (Carboni 12). In this face we consider Vinegar which made from fermented wine, apple juice, or grain. Vinegar is made up of 5 per centum acetic acid, thus it turns out to be mild acid. Vinegar has the capability to dissolve grease, mineral deposits, sterilize of rid soap traces, deodorize, take out mildew or wax backlog, and refine some metals. Vinegar is able to clean stone or brick, and is used in making some carpet killing agents as an ingredient. Vinegar can be
