  1. NH4OH(ammonia) + HIn(phenolphthalein) <-> NH4In(pink) + H2O
    It drives backward when ammonia starts to evaporate as its boiling pt is less than water
    So it will become less in concentration and eqb will shift backwards
    I knew it bt never thot of doing such a beautiful experiment <3

  2. theres another way to change a flower color. (it has to be real) here is what you need

    1. Food coloring

    2. any real flower

    3. wineglass

    put water in your wine glass then put a food coloring color in it then put your flower in the glass for 1/2 hours then pull it out and its that color!

  3. what is happening is that original chemical he has used to spray the flower in the beginning of the video shows the acidity level of the ammonia that he sprays on later. I have seen this done with larger proportions of chemicals.

  4. Phenolphthalein is a very common pH tester used to find basic materials. Ammonia is an incredibly strong base, so when it is introduced to the phenolphthalein, it turns pink to indicate the base's presence.

  5. My chemistry teacher sophomore year used Phenolphthalein to spell out "welcome to chemistry" on some paper towels and then sprayed them with windex on the first class XD. We all thought it was the coolest thing ever
