How Do You Make Ph Indicator Solution For Chemistry Experiments?
Testing substances for acid or base content (pH) is a standard part of any basic chemistry course. You can easily make your own pH indicator solution that will turn bright pink in the presence of an acid and green in the presence of a base. Put several red cabbage leaves into the pot and add 1 cup of water. Put the lid on the pot and boil the leaves for 5 minutes. The water in the pot should be very red. Let the cabbage water cool. Pour off the red water into a storage jar, straining out any pieces of cabbage leaf. (Usually, the leaves won’t break apart too much, but if yours do and you need help straining the pieces, try using a coffee filter or a paper towel.) Use your indicator solution right away, or refrigerate it for future use. To use your indicator solution, put 2 tsp. of solution into a small jar or test tube, then add 1 tsp. of your test solution. If the test solution is acidic (such as lemon juice or vinegar), the indicator solution will turn bright pink. If the test solutio
