  19. Hardness in Drinking-water - who.int

    Water hardness is the traditional measure of the capacity of water to react with soap, hard water requiring considerably more soap to produce a lather. Hard water often produces a noticeable deposit of precipitate (e.g. insoluble metals, soaps or salts) in containers, including bathtub ring. It is not caused by a single substance but by a

  20. How to Convert PPM to Grains in Water Hardness, Sciencing

    Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon. For example, say you have a water hardness value of 180 ppm. Work out 180 ÷ 17.1 = 10.526.

  23. Annealing (metallurgy) - Wikipedia

    In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable.It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for a suitable amount of time, and then cooling.

  24. Determination of Hardness of Water by EDTA Titration

    In this article, we are going to talk about the determination of hardness of water by EDTA titration method.The causes of hardness of water is by multivalent metallic cations, which react with soap to form precipitates and with certain anions present in water to form scale.. The primary cations causing hardness are calcium, magnesium, strontium, ferrous ion, and manganous ions.
