"PROGRAM IDEAS"
"CABBAGE WATER"

CHOP one large red cabbage into small pieces. Note: Blackberries, red onions, or even hibiscus flowers can be used as a substitute.

SIMMER the cabbage pieces until the water turns a deep shade of purple.

ALLOW the water to cool.

REFRIGERATE when not in use.

Red cabbage water is an indicator of pH. Although it can't be used to determine exact pH, it can distinguish between acid (pH of 0 to 6), neutral (pH near 7), and base (pH of 8 to 14).

If the indicator turns the solution red or pink, the solution is an acid.

A purple solution indicates that it is neutral, neither an acid nor a base.

If the indicator turns the solution blue or green, the solution is a base.
