What pigments are removed by boiling the leaves in water?
Chlorophyll is the main pigment that is removed by boiling leaves in water. This process breaks down the chlorophyll molecules, leading to the loss of green color and the exposure of other pigments such as carotenoids and anthocyanins.
What pigments are removed by boiling water?
Boiling water can help remove water-soluble pigments like chlorophyll in green vegetables or anthocyanins in red cabbage. These pigments are sensitive to heat and may leach out into the water during boiling, resulting in faded color in the food.
Do Calcium bicarbonate salts cause hardness to the water?
Yes. it causes temporary hardness of water, which can be generally removed by boiling water.
Why temporary hardness is removed from water by boiling but permanent hardness is not?
Permanent hardness is hardness (mineral content) that cannot be removed by boiling. It is usually caused by the presence in the water of calcium and magnesium sulphates or chlorides which become more soluble as the temperature rises.
Why does the water in a car radiator sometimes boil explosively when the radiator cap is removed?
Because when the cap is removed the liquid inside wants to start cooling itself. The heat energy is released by boiling.

How do you clean the blades in a dishwasher?

What are the two form of hardness found in water?
Hardness in water is usually characterised as temporary or permanent. Both are due to the presence of calcium or magnesium ions. If they are present as the hydrogen carbonate, when the water is boiled this is converted to the carbonate which precipitates out as a solid, leaving water which is no longer hard, so this is called temporary hardness. If they are present as the sulfate the solution is unaffected by boiling, and this is called permanent hardness.
When boiling water will it remove all the contaminants?
Boiling water will effectively kill most bacteria, viruses, and parasites that may be present in the water. However, it will not remove chemical contaminants or heavy metals. To remove these types of contaminants, additional water treatment methods such as filtration or distillation may be necessary.
