Question: Catalysis and Chemistry Experiments for kids (science fair)?
I would like to ask if anybody has some suggestions for catalysis experiments for kids, namely with activated carbon. Does it adsorb for example some colored compoud of water or so? Or alternatively could you suggest a website where I can find suitable information? Thank you!
Answer: i don’t know why you specifically want the experament to do with carbon, but i’m sure you can find what you want here:

Welcome to Science Experiments Blog
Science experiments are key to understanding how things are. This Science Experiments website is dedicated to discussing simple science experiments.
Many science experiments discussed here can be used as science fair experiments. Among science experiments discussed on this website are easy Science Experiments For Kids, some are middle school science experiments, and we aim to add more high school science experiments.
Some science experiments are very Cool Science Experiments and are sometimes used as magic tricks. You can also use science experiments here for Science Experiment Ideas such as ideas for science fair experiment. Examples of simple science experiments presented on this Science Experiments website are Seed Germination science experiments, Fossilization science experiments, and egg drop experiments.
There are so many simple science experiments one can do at home. This Science Experiments website discuss some of these more common science experiments. Many other science experiments have not been included because of space and time. We will be adding more Science Experiments Projects in the near future. So, check back on our website to read more about new science experiments. You can also use the link below to bookmark this page. If you have questions, please use our contact form.
Question: PLEASE i have NO IDEA what to do on this TITRATION lab experiment question? i would appreciate some help ?
I did an experiment and found that the mean concentration (M) of HC2H3O2 (acetic acid) is 838. I also initially had the molarity of NaOH to be 0.25, and the volume of NaOH to be 34 mL.
they are asking me this:
the manufacturer of the vinegar used in this experiment claims that the vinegar contains 5% acetic acid by weight. Use your results and a density of 1.0 g/mL to investigate this claim.
oops, i meant the acetic acid’s molarity was 8.38 M
Answer: Wow, 838 M acetic acid? Are you sure you didn’t do something wrong? The most concentrated I’ve used was 15-20 M acetic acid.
I would say that the manufacturer of your vinegar is trying to kill you if they wanted to sell you 838 M acetic acid, or you got a really good deal.
