Jen500 Posted September 10, 2008 Share Posted September 10, 2008 Help! The next RS4K (#5) experiment uses ammonia and vinegar. I can't take the odor from the ammonia anymore. Is there anything else that will work just as well? Quote Link to comment Share on other sites More sharing options...
Blue Hen Posted September 10, 2008 Share Posted September 10, 2008 What's the experiment? Purpose? What does it call for you to do? Quote Link to comment Share on other sites More sharing options...

Pata Posted September 11, 2008 Share Posted September 11, 2008 Try baking soda dissolved water. I think that you doing an acid/base experiment with cabbage indicator. Vinegar is you acid and baking soda should be able to act as your base. It's probably going to fizz quite a bit, so leave room for that in your jar. I think that's right, but I'm going completely off of memory and it's been 10 years since my last chem class! Quote Link to comment Share on other sites More sharing options...
readwithem Posted September 11, 2008 Share Posted September 11, 2008 Would it have to be regular ammonia? I've got some lemon scented ammonia and it doesn't smell like ammonia at all. Quote Link to comment Share on other sites More sharing options...
Blue Hen Posted September 11, 2008 Share Posted September 11, 2008 To determine how much ammonia is needed to change the color of vinegar from red to green with the use of red cabbage indicator. Instead of ammonia use baking soda, baking powder, antacids dissolved in water, try different dish soaps, do you have some lime with your garden supplies? experiment with different household 'supplies' and see which ones are acid and which are base. The base ones will turn it from red to green. One of the things that is fun to do with this experiment is to repeatedly turn the solution from red to green to red to green..... Use lemon juice to turn it back. Carole Quote Link to comment Share on other sites More sharing options...
Jen500 Posted September 11, 2008 Author Share Posted September 11, 2008 Thanks for all the ideas! We'll just try using a variety of bases. (We just did the exp. making red cabbage indicator strips and tested various items, and then used ph and litmus paper too, so you'd think this wouldn't be so hard for me :001_huh:) And the idea to turn in back is great!
