Chemical Changes
By taking some limewater and blowing one's breath into it a fine white powder will be formed in the water. By adding some common salt to a solution of nitrate of silver a thick white powder is produced which, if placed in the sunlight, will turn brown. Pour the juice of a red cabbage into a test tube or thin glass bottle, drop in very gradually a solution of washing soda, shaking the bottle every time you put the washing soda in, and you will see the red solution gradually turning blue. Go on adding the soda solution, and the blue color will give way to green.
