'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).
