Hard water is high in dissolved minerals, largely calcium and magnesium. You may have felt the effects of hard water, literally, the last time you washed your hands. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Depending on the hardness of your water, after using soap to wash you may have felt like there was a film of residue left on your hands. In hard water, soap reacts with the calcium (which is relatively high in hard water) to form &#8220;soap scum&#8221;. When using hard water, more soap or detergent is needed to get things clean, be it your hands, hair, or your laundry. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">General guidelines for the classification of waters are 0 to 60 mg\/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg\/L as moderately hard; 121 to 180 mg\/L as hard; and more than 180 mg\/L as very hard.<\/span><\/p>\n<p><img loading=\"lazy\" class=\"alignnone wp-image-139344\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/hard-water-film_0-1.jpg\" alt=\"Water hardness\" width=\"1100\" height=\"741\" srcset=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/hard-water-film_0-1.jpg?v=1647110846 340w, https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/hard-water-film_0-1-300x202.jpg?v=1647110846 300w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"TYPES_OF_WATER_HARDNESS\"><\/span>TYPES OF WATER HARDNESS<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The hardness of water can be classified into two types:<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Temporary Hardness <\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Temporary hardness is water hardness due to the presence of calcium and magnesium carbonates and bicarbonates, which can be precipitated by heating the water.
