Ion-exchange reaction | chemical reaction | Britannica

8/8/2020· In terms of a chemical equation, the process is 2K + + Ca 2+ (soil) Ca 2+ + 2K + (soil), in which the double arrow indies that the exchange is reversible. In Way’s experiment, the process was pushed to completion (that is, the equilibrium was pushed to the right) because the water trickling through the soil continually came in contact with fresh calcium-loaded soil.

Water Hardness - Department of Chemistry

For example, when hard water is heated, Ca 2+ ions react with bicarbonate (HCO 3-) ions to form insoluble calcium carbonate (CaCO 3), as shown in Equation 1. (1) This precipitate, known as scale, coats the vessels in which the water is heated, producing the mineral deposits on your cooking dishes.

water treatment - the calcium-carbonate balance - …

As the CO 2 content has an influence on pH, we can conclude that, for a given mineralisation (fixed CaH and M-alk.), there will be a pH value for the equilibrium between this water and the calcium carbonate: this value is termed the Langelier pH or saturation pH hence the designation "pH S" (the corresponding CO 2 content then being know as the balancing CO 2, a concept that will be quantified
