does anyone know a good website i could look at so i could answer this question: ?

Explain how indicators work using a chemical reaction as part of your explanation.

Any websites? please?
thank you!!

Here is a god web site chock full of information. It may be more than you wanted but you can go through it and take what you need. If you want to look for other sites, go to www.google.com and type in pH indicators. You can also look at howstuffworks on google.(Broken Link Removed)
