'In addition, when the plant is watered using hard water, a white coating or segmentation (
Calcium bicarbonate of carbonate) is formed on the surface of the soil.
Kabil pointed out that Egyptian exports to Gabon included a mix of taste and smell additives, public transportation buses and tourism buses, glasses of different kinds, paints, aluminum, plumbing equipment, cooking equipment, wood furniture, and
calcium bicarbonate. Imports included steel and iron products only.
Calcium Chloride (CaCl2), Calcium sulphate (CaSO4), Magnesium chloride (MgCl2), Magnesium sulphate (MgSO4), Iron chloride (FeCl2), Iron sulphate (FeSO4),
Calcium bicarbonate Ca(HCO3)2, Magnesium bicarbonate Mg(HCO3)2 and Iron bicarbonate Fe(HCO3)2 are of analytical grade and all from Merck.
2012) that the mechanism of calcium liberation from the insoluble calcium carbonate is based on the formation of
calcium bicarbonate Ca(HCO3)2, according to the reaction:
(A) arid (B) Mostly
calcium bicarbonate, but also magnesium bicarbonate.
Serum calcium may bind to carbonate and bicarbonate anions resulting in the formation of calcium carbonate and
calcium bicarbonate (CaHC[O.sub.3]+), respectively [96,109,110].
PEO, Carboxymethyl ethyl cellulose,
calcium bicarbonate and magnesium stearate were obtained as gift samples from Hetero drugs Ltd (Hyderabad, India).
Adding calcium carbonate to this solution touches off a reaction that produces
calcium bicarbonate. That is similar to the way in which C[O.sub.2] is naturally removed from the atmosphere over geologic time.
The water passing through carbonate rocks (limestone and dolomite) causes water with
calcium bicarbonate or calcium / magnesium chemism.
When alum is added to wastewater, it forms the precipitate of Al [(OH).sub.3] on reaction with
calcium bicarbonate alkalinity, as follows (Tchobanoglous et al., 2003):
Formation of
calcium bicarbonate: (CaC[O.sub.3(s)] + C[O.sub.2(g)] + [H.sub.2][O.sub.(l)] [right arrow] Ca[(HC[O.sub.3]).sub.2(aq)]
Pre-treated (raw) mains water contains
calcium bicarbonate which when heated, decomposes to form calcium carbonate (limescale).
