A major concept applicable to problems dealing with the behavior of carbonic acid and carbonate minerals in seawater is the idea of a “constant ionic medium.” This concept is based on the observation that the salt in seawater has almost constant composition, i.e., the ratios of the major ...

Sodium carbonate extraction followed by neutralization with an ion exchange resin is generally the preferred technique. This is usually followed up by modern analytical techniques. For air-entraining admixtures, microscopy is used to check that a good bubble size distribution has been achieved. SEM is...

Population balance equationAcid stimulation is used in carbonate reservoirs to bypass formation damage. Carbonate reservoirs are highly heterogeneous with layers of large permeability variation. For even distribution of acid between layers, we have developed a new acid diversion system using nanoparticles. ...
The chloride ion or any anions in acids can combine with cations, such as the metal ion in a carbonate compound. In this case, the chloride ion will combine with the calcium ion, to make the compound calcium chloride. You will of course, need to use the ionic charges to write the cor...
A et al. (10) hypothesized that acute changes in acid-base status three-point calibration line (using 0, 10, and 25 mM sodium produced the wide variation in pK1. We were unable to confirm carbonate solutions) was determined before each measurement. this hypothesis in newborn lambs in ...
It has been suggested that the hydrocarbonate salt of the local anesthetic penetrates membranes more rapidly than the conventional formulation and that the injected carbon dioxide diffusing into the nerve trunk lowers the internal pH and concentrates local anesthetic molecules by ion trapping. Although ...
An unsubstituted dienolate, generated from the reaction of an NHC catalyst and methyl (E)-(4-oxobut-2-en-1-yl)carbonate, undergoes a subsequent [4 + 2] annulation reaction with isatins to afford spirooxindole 5,6-dihydro-2H-pyran-2-ones in moderate-to-good yields with moderate-to-good...
