In order to make this kind of an indicator, you need: RED CABBAGE, A MIXER, WATER, STRAINER, ACID, BASE, BEAKER (or a glass).
Now, take a few of the red cabbage leaves and put them in the mixer, after that, put water into the mixer. Now: MIX! When you mix, strain off the cabbage-leaf parts into a beaker and you're ready to go. If you pour hydrochloric acid, the juice turns red, if you put ammonia, it turns green, if you put a solution of sodium hydroxide, it turns yellow. Of course, these are all lab-grade chemicals. You can also use (Lemon) Citric Acid, Acetic Acid(Vinegar), Sodium Bicarbonate(Baking Soda)...Hope I helped..! :)

What does red cabbage indicator smell like?
The red-cabbage indicator smells like cabbage, nothing else...
Why is the universal indicator more useful than the red cabbage?
The universal indicator is better than the red cabbage indicator because the universal indicator has a wider range of pH that it can explain why a substance is acidic or basic. The red cabbage indicator only tests the substance if it is an acid or a base. Also, the universal indicators are made carefully and it is manufactured in a precise manner so the results are very reliable. Red cabbage indicators will vary in concentration which could cause errors to occur in determining the pH of a substance.

Why is red cabbage indicator not a good experiment to measure buffering capacity?
A buffer absorbs or releases excess hydrogen ions, making the solution hold at a steady pH. Since red cabbage indicator makes a good pH indicator, it has a neutral pH. any amount of acids or bases added would change the pH of the red cabbage juices. If it made a good buffer, it would not make a good pH indicator.
