Merge Hard water date January 2010 Wikify date October 2010 Carbonate hardness , or carbonate alkalinity is a measure of the alkalinity of water caused by the presence of carbonate CO sub 3 sub sup 2 sup and bicarbonate HCO sub 3 sub sup sup ions. It is usually expressed either as parts per million Parts per million ppm or Gram per litre mg L , or in degrees KH from the German Karbonathä rte . One German degree of carbonate hardness is equivalent to about 17.848 milligrams of calcium carbonate CaCO sub 3 sub per litre of water 17.848 ppm . Both measurements mg L or KH are usually expressed as CaCO sub 3 sub &ndash meaning the concentration of carbonate expressed as if calcium carbonate were the sole source of carbonate ions. Bicarbonate ions only contribute half as much carbonate hardness as carbonate ions, so bicarbonates that are present in the water are converted to an equivalent concentration of carbonates when determining KH. For example An aqueous solution containing 120 mg Sodium Bicarbonate NaHCO sub 3 sub baking soda per litre of water will contain 1.4285 mmol L of bicarbonate, since the molar mass of baking soda is 84.007 g mol. This is equivalent in carbonate hardness to a solution containing 0.71423 mmol L of carbonate, or 71.485 mg L of calcium carbonate molar mass 100.09 g mol . Since one degree KH 17.848 mg L CaCO sub 3 sub , this solution has a KH of 4.0052 degrees. Carbonate hardness supplements non carbonate a.k.a permanent hardness where ... heated.

Carbonate and bicarbonate anions contribute to alkalinity due to their basic chemistry basic nature, hence their ability to neutralize acid . Mathematically, the carbonate anion concentration is counted twice due to its ability to neutralize two proton s, while bicarbonate is counted once as it can neutralize one proton. Carbonate alkalinity is often the major component of a natural solution s total alkalinity . It is an important factor in understanding large scale environmental interactions based on simple pH and carbon dioxide measurements. math text CT mEq L text HCO 3 2 text CO 3 2 math Alkalinity is commonly expressed as mg L CaCO sub 3 sub because CaCO sub 3 sub has an equivalent weight of 50.

Image Carbonate ester.png thumb Chemical structure of the carbonate ester group. A carbonate ester organic carbonate, organocarbonate is a functional group in organic chemistry consisting of a carbonyl group flanked by two alkoxy groups. The general structure of these carbonates is R sub 1 sub O C O OR sub 2 sub and they are related to ester s R sub 1 sub O C O R and ether s R sub 1 sub OR sub 2 sub and also to the inorganic chemistry inorganic carbonate s. Carbonate esters are used as protecting group for diol s. A classic reagent is phosgene but more user friendly reagents exist such as carbonyl diimidazole . Ethylene carbonate and Propylene carbonate are used as a solvent . Dimethyl carbonate is used as a methylation methylating reagent. In many applications a carbonate group replaces an ester group for example in Cholesteryl oleyl carbonate . Polycarbonate s are an important class of polymers.

Calcite can be either solvation dissolved by groundwater or precipitate d by groundwater, depending on several factors including the water temperature, acidity pH , and dissolved ion concentrations. Calcite exhibits an unusual characteristic called retrograde solubility in which it becomes less soluble in water as the temperature increases. When conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together or it can fill fractures. Karst topography and cave s develop in carbonate rocks due to their solubility in dilute acid ic groundwater .

Cap carbonates are layers of distinctively textured carbonate rock geology rock s which typically form the uppermost layer of sedimentary sequences reflecting major glaciations in the geological record. The rising temperatures, and increased oceanic surface area due to reduced ice cover and rising sea levels at the end of a glaciation increase the rate of precipitation meteorology precipitation . High concentrations of greenhouse gas ses such as carbon dioxide CO sub 2 sub must build up in the atmosphere to overcome the effect of the high reflectivity albedo of ice and allow temperatures to rise sufficiently to begin melting. Increased precipitation dissolves carbon dioxide from the atmosphere, falling as a weak carbonic acid acid rain . This would weather exposed silicate and carbonate rock, including readily attacked glacial debris, which would releasing large amounts of calcium.
