Litmus Test at Home 4 May 2011

Looking at the purple cabbage which we prepared for dinner and lemon which we added to our fruit juice, I recalled the home-made litmus test.

Crush the cabbage with some hot water which create some purple-blue colour liquid. Divide into three cups.
Add lemon to the first cup and it turns pink = alkali.
And if you add some baking soda to the second cup,  it turns blue = acid.
