The acid will be neutralised making it virtually harmless. The pH of our bodies signalises our health and how healthy our body is. To all of you out there, the very same happened to me and I'm sorry I didn't address this issue earlier. pH plays a major role in chemistry and chemistry is constantly shaping our world with advances in medicine, materials and health.

Blue litmus paper turns red when a solution is acidic; red litmus paper turns blue in basic solutions. We are continually trying to interest her in the sciences. Created: Apr 12, 2019| Updated: May 19, 2019. Thank you for this article. Neutral litmus paper is purple. Litmus can also be prepared as an aqueous solution that functions similarly. I WANT TO SHOW MY DAUGHTER TO DO EXPERIMET AT HOME FOR CHEMISTRY AND FOR PHYSICS. Slightly more alkaline blood signalises health whilst an overall acidic body may signalise a less healthy metabolism. Susan W (author) from The British Isles, Europe on May 26, 2015: tirelesstraveler - Thanks for the great comments! If you have red and blue litmus paper , you can test different solutions for whether they are acids or bases. Thank you for your questions and I am pleased to have helped!

For a great pH paper experiment, check out the end of this post! An indicator such as methyl orange or litmus is put into the base.

I have found that the 'blue' is only a hue and not distinctly blue after waiting for about 30 seconds. The emergency team will add a base such as lime to the acid.
