When the water boils, there is white sediment, which should be scale. The main components of scale are calcium carbonate and magnesium carbonate, which do not affect the drinking of water. A layer of gauze can also be used to filter out these white sediments.
Sometimes when the water is boiled, you will find some white sediments under the kettle. These sediments are actually scale. The main components are calcium carbonate and magnesium carbonate, which can be drunk after boiling.
After boiling the water, the phenomenon of white sediment in the water mostly occurs in the north of China, because the precipitation in the north is less, the residents' drinking water is mostly groundwater, there are more minerals, and there are more white sediment in the water.
After the water is boiled, the water with white sediment can be drunk, but you can't drink this sediment directly. You can cover the water outlet of the kettle with a layer of yarn, filter out this sediment and then drink it.
