With this in your water, it is difficult to wash because the hardness prevents soap from lathering. Hardness also leads to scaling in pipes and water heaters. Hardness is described in grains per gallon (gpg) or parts per million (ppm).

You can perform the unit conversion the other way, too. Remember, for dilute solutions, you can use the approximation that 1 ppm is 1 mg/L. Use the atomic masses from the periodic table to find the molar mass of the solute. 2 dagar sedan · Soft water has fewer than 75 ppm (parts per million) of minerals dissolved in it. As a result, soft water is considered fairly pure and drinkable. Because of the very low amount of minerals dissolved in it, it reacts well with cleaners such as household cleansers or laundry detergent and does not leave behind a residue.
