pH Testing

To compute the pH value of a liquid with this app, you need to mix one part of the liquid with two parts of cabbage solution.

To make the cabbage solution, you need:

+ Red Cabbage

+ A pan

+ Water

1) Chop the red cabbage

2) Boil the red cabbage in water for about 1 hour

3) Once boiled, strain to remove the cabbage pieces

Once you have mixed your liquid with the cabbage solution, use the CAPTURE button to take an image of the mixture, and the app will show the pH value of your liquid.
