You shouldn't be able to place a beetroot in water at a temperature of 0° C, because that is the temperature at which water freezes.
on acids beetroot juice changes to pink or reddish blue
Percentage of water in beets stands at around 75 percent.
The water become red colored.
oxygen
No. To get them to float they must be placed on something light.
The color is unchanged.
Refraction of light occurs when a light pass through a glass that is filled with water. In this process, the light changes direction as it changes transmission medium.
A drop of water placed on the page of a book magnifies the printing beneath it because the water acts as a lens. The water refracts the light making the lettering look bigger.
Not in many ways, if a prism is placed in water, then it will refract light. Light is already scattered even when passing through clear water, so the refraction is very hard to see.
if you make a baking soda solution(by mixing water with it), and using a cotton bud(which is dipped from the solution), you will have to write a message or text on a sheet of paper and then wait till it dries. Now take a slice of beetroot and rub it over the paper smoothly. The result is that the message will appear white after some 12 hours unlike how it was when you first rubed the slice over it. This can be considered as the reaction of baking soda solution with beetroot. Concerning the reaction between beetroot and plain baking soda, there is no reaction to happen.
