yay, great fun , and works for purple sprouting broccolit too. (in fact if you want to do some fun kitchen /garden chemistry, you can try all sorts of petals and veg. beetroot is good I seem to recall!)

oh yes , what colour?-- it goes turquoise in alkali and pink in acid. Bicarbonate of soda and lemon juice are all you need for a fun afternoon with your 8 year old.

It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.

Red cabbage juice contains a class of chemical compounds known as anthocyanins. The color of anthocyanin molecules in solution depends on how acidic or basic the solution is. In a strongly acid solution, anthocyanins will appear red. In a neutral solution, anthocyanins appear purple. In weakly basic solutions anthocyanins appear blue, while in strongly basic solutions they will appear green. In extremely basic solutions, the anthocyanins will appear yellow.

Because ammonia is a base, spraying ammonia into a glass containing cabbage juice (which contains anthocyanins) will most likely turn green.

Red cabbage juice will turn pink when an acid is added to it. Due to the acids in a carbonated drink, 7up till turn the juice a pink colour.

blue-pinky colour.

They are called indicators.

Not really. The main thing is that green vegetables have less calorie and carbohydrate value than coloured veg.

Of course, even using red cabbage on the csd you'd still lose considerable amounts of weight - just a little less than if you used green cabbage.

There exist many delicious cabbage soup recipe variations. If you use red cabbage only on one day of the 7 day diet week it won't harm your weight loss success.

Because tooth paste is a base because anything that turns a blue or green when mixed with red cabbage juice(indicator) is a base.

It depends on the pH of the base, but the juice will turn some sort of greenish yellow.

It will turn either blue or green, both a hue of blue. The reason of this is that Red Cabbage Juice is an indicator, which is used to see wether an object or chemical is an acid or a base. If the object is an acid it will turn a hue of pink, and if it is a base, it will turn a hue of blue. Which is why baking soda mixed with Red Cabbage Juice will turn blue or green.

Any substance with a pH of 7.

If the pH of a detergent is usyally greater then 7 the juice of red cabbage become blue to green in this solution.

take 1 part of starch and 2 parts of water - mix

take 1 part calcium chloride powder and rapidly mix with starch suspension

it will be heated in exothermic reaction of starch gelation

gel has properties of a rubber

put a piece of a gel i n microwave an it will be foamed
