Answer 2

Answer:

Concept :

Dissolved calcium, magnesium, and other heavy metal chlorides, sulphates, and nitrates are present. It is measured as the weight in milligrammes of CaCO3 (equal to all substances that cause hardness in one million milligrammes of water) that is present. PPM stands for parts per million (ppm). A litre of water's worth of all the substances that cause hardness may also be stated as the weight in milligrammes of CaCO3. Hardness is measured in both degree and extent.

Explanation:

• Presence of dissolved The chlorides and sulphates of Ca, Mg, and Fe cause the water to become permanently hard. It is also known as non-carbonate hardness (NCH).
• Boiling can not remove permanent hardness, but other chemical techniques such as the lime-soda method, the zeolite approach, and ion exchange techniques can.
• The property of water that prevents a significant amount of leather or foam from forming is its hardness.
• It happens because of the existence of carbonates, bicarbonates, sulphates, calcium- and magnesium-chloride chlorides (Ca and Mg). Water hardness is caused by the dissolved minerals Ca2+, Mg2+, Al3, and other heavy metals.
• Particularly because of Magnesium Sulphate, Magnesium Bicarbonate, Magnesium Chloride, Calcium Sulphate, and Calcium Bicarbonate.
