Mohs scale of mineral hardness - Simple English Wikipedia ...

Mohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist who invented a scale of hardness based on the ability of one mineral to scratch another. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials.

Drinking Water Treatment: Salt-Free Water 'Softener' Options

The removal of hardness minerals from water is often termed "softening." The most common method of removing hardness minerals from water at the residential or small commercial scale is an ion exchange water softener. Water softeners work by exchanging sodium or potassium on the surface of a resin with calcium and magnesium in the water.
