Hardness of water is due to the presence of calcium and magnesium salts.
Genrally, soaps consist of Na salts of higher falty acods like sterai. oleic, obrc etc. which are highly soluble in water amd thus exert their cleansing action . If Ca and Mg salts are present , these react with soluble Na soap to form insoluble salts of Ca and Mg.

∙ 14y agoThey are a combination of corrosion products from the system - such as various oxides of iron, and precipitated salts from the water. The typical precipitate is the highly insoluble calcium carbonate - it is formed when calcium hydrogencarbonate, sparingly soluble in water, is heated.
As water evaporates continuously the concentration of the dissolved salts increases.when the saturation points are reached,the salts are precipitated.If the precipitate is soft,loose and slimy ,it is sludge .on the otherhand if the precipitate is hard and adherent it is scale

What is the difference between sludge and scale?
Hard Scale(Scale) - Forms in steam boiler -Has the appearance of a white and brown concentration -smooth texture Soft Scale(Sludge) -Forms in the hot water heaters -Appears as a thick ,brown or black sludge
What is calgon process.its is the process to remove hardness of water?
Yes. It is addition of calgon i.e.: sodium hexa metaphosphate in boiler water to prevent the formation of scale and sludge. Calgon removes scale forming Ca
Why is dried sludge used as a fertiliser on the land?
dried sludge is used as fertilizers as normal sludge is wet and contains bacteria which can harm the crops.

What are some critics' ideal boilers?
There are many ideal boilers for critics. Some ideal boilers for critics include the Buderus boilers, the ORLAN boilers, and lastly the Crown Boiler company boilers.
Where frictionis disadvantageous?
In bearings.
What Is disadvantageous trait?
Any character that is not favored by selection is disadvantageous e.g. loss of pollen tube in land environment .
Why Demineralised water used in boiler?
dimineralised water is also preferable to tap water for use in model steam engine boilers and model engines of other types. Mineral build-up resulting from the use of tap water in model boilers can severely reduce the efficiency of the boilers if run for long periods. This build-up is called boiler scale.
What is the antonym for the word advantageous?
Disadvantageous
Why steam boilers are coil type boilers?
All boilers are not coil type think of the pork chop steam boilers AKA cast iron sectional
