experiments with acids

When you poured the four glasses back into the pitcher, the phenolphthalein reacted to the sodium carbonate, a base, and turned the solution to bright pink “kool-aid.” To change it back to “water,” all you had to do was add the acidic vinegar, which turned the phenolphthalein colorless again. Open Mon-Fri: 8A-5P In lesson 2, selecting zinc and sulfuric acid as the example to follow through to producing crystals of the salt is governed by the need to have a salt that crystallises easily. Acids and bases are chemicals that are dangerous to human tissue. Solid sodium carbonate. Experiment to localize proteins in a cell: Requirements: Fresh tissues, razor, acid fuchcin, acetic acid, glycerine jelly, slides, cover slips. Indicators allow us to see if a chemical reaction has occurred by changing a physical characteristic (color, smell, temperature, etc.). See more ideas about acid base, experiments, teaching science. Hydrangeas (Hydrangea macrophylla) are also good indicators of pH. All liquids are categorized as acids or bases and we have an entire scale that tells you how acidic or basic something is: the pH Scale. Litmus solution. Here are the pH levels of some other substances that you might test: Human blood has an ideal pH of 7.4; even slight fluctuations can seriously affect our bodies. This is a fiery twist on acid/base experiments. Acids and bases can neutralise each other. Some great and common bases include baking soda, milk of magnesia, and dish soap. To get the rainbow effect, another scientific principle is at work—density. Depending on the pH of the liquid, the cabbage turns various shades of pink, purple, or green!
