Science Buddies: "Ask an Expert"

How would I begin to do this experiment and when I'm finished, how do I test that the material I get at the end is actually water? PLEASE HELP ASAP. Thank you.

Hi!

I can't get onto the website, but I think it may help. This experiment is the same one you are doing, so I believe it will give you the details of the project. However, you must become a member and pay $10. Here is the site:

Hope this helps!

Hi Joane,

I'm going to answer your question with lots of questions to get you started on finding what you need to know for this.

What made you pick those starting materials? (ink, vinegar, milk)
Do you already have an idea whether they contain water? or could some of them be a pure substance ie. cannot be separated into components? what would you guess? can you do a google search to find out?
what is a "suspension"?

Do you want to separate them completely into their components or would it be ok to just obtain part of the water from them? or do you want to obtain pure water?

Have you done any experiments before to filter things?

Do you know what happens to milk if you boil it?

What are some of the properties of water that you know that you might be able to test? do you know the pH of water?

If you are having trouble finding answers to these I am happy to help,

Caroline

Hi Joane,

Building on what caroline said, I would suggest you talk to the chemistry teacher at your school. What science class are you taking right now? If not chemistry, I'm sure your teacher would know of the chemistry teacher at your school and you could ask through him/her.

Hope this helps,
