Are you having trouble finding 'lab testing for acids and bases'? You will find the answers here.
Litmus test is a biological acid-base indicator extracted from a eccentric of lichen. If you have bloody and blue litmus test paper, you buttocks test different solutions for whether they are acids operating room bases. Blue litmus test paper turns bloody when a resolution is acidic; bloody litmus paper turns blue in alkaline solutions.
