Product as described Review by
I used this with the directions on the website for making a rainbow using vinegar and sodium carbonate. The experiment worked well and really wowed the kids.
good for use in pH experiments Review by
Bought the universal indicator for use in pH experiments. It is so easy to use and I like it much better than using litmus paper. I now take it everywhere we go so we can do pH experiments "on the fly", like testing the pH of the pond water when we go fishing, or testing different foods and liquids to see if they are alkali or acidic.
Excellent product Review by
Home Science tools makes it easy to do fun experiments on a small scale. I am glad that this product is available in this small quantity. Creating pencil electrodes, dunking them into this indicator and watching the different colors develop at each electrode is good fodder for discussions on electrochemistry, acid-base equilibria and the nature of indicators.
Exactly what I wanted Review by
I've been using this indicator for a few years now for a science fair I participate in at a local school. The indicator does exactly what it's supposed to do and it can sit on a shelf for a year and still do it again the when the annual fair comes around again. Highly recommended.
the supply that keeps us experimenting! Review by
What a wonderful pondering point this chemical offers. The deep green indicator sits on the top of the water, when vinegar is added a bright and cheery pink develops! We have done this so many times, and the kids in my science club have nominated it as a "join the science fun" experiment on our up coming science night. Thankfully, I think I have enough to support an evening of young explorers to discover the "OOh, Aah!" factor of chemistry!
