Bicarbonate increase

The most common source is the supersaturation and subsequent scaling of minerals originating in the MU water. Insoluble calcium carbonate in the form of calcite (CaC03) resulting from the thermal decomposition of soluble calcium bicarbonate [Ca(HC03)2] is a classic example. Calcium carbonate quickly forms a white, friable deposit. In addition, the hydrolysis of excess bicarbonate increases... [Pg.144]

Sodium bicarbonate increases renal tubular reabsorption of amphetamine, resulting in a prolonged amphetamine elimination half-life be aware of this combination. [Pg.533]

Acetazoiamide, aminophyiiine, sodium bicarbonate increased iithium excretion. [Pg.57]

The addition of sodium bicarbonate increases the potency of the local anesthetics two to four times for direct application or injection into nerve tranks and probably for subdural injection and on application to mucous surfaces. This is due to the easier penetration of the free anesthetic bases, as compared with their salts. For these purposes, the usual solutions of the anesthetic salts may be mixed with an equal volume of 0.5% sodium bicarbonate solution, without loss of efficiency, and with a saving of one half of the anesthetic, and correspondingly smaller danger of accidents. The mixtures, however, do not keep well, and must be made just before use. Alkalinization or buffering has no advantage for hypodermic or intradermic injections, because these do not require much penetration. Procaine base dissolved by the aid of carbon dioxide is also more potent than the hydrochloride when applied to the cornea, but not for intramuscular injection. [Pg.261]

The electrochemical oxidation of sodium tetraborate to perborate is accompanied with a corresponding decrease in alkalinity of the electrolyte i. e. the quantity of carbonate decreases and that of bicarbonate increases during the alectrolysis according to the equation ... [Pg.425]

Antacids Indometacin ( other NSAIDs) Variable effects of different formulations aluminium-containing antacids reduce the rate and extent of absorption of indometacin sodium bicarbonate increases the rate and extent of absorption of indometacin No action required, unless a marked reduction in absorption results in a poor response to the NSAID, in which case dosages may need to be increased or the antacid withdrawn... [Pg.2574]

In conclusion, the administration of sodium bicarbonate increases plasma pH but has the opposite effect in the CSF and intracellular fluid, which may be extremely detrimental to the acidotic patient. It may further increase the plasma lactate and sodium concentrations and may decrease the ionized calcium concentration. It corrects one laboratory value (pH) without addressing the underlying pathophysiology (poor tissue perfusion), by imposing a hypematremic alkalosis on an already deranged metabolic balance. [Pg.336]

Whole saliva (spit) is a dilute, viscous solution of proteins and shed epithelial cells. The major electrolytes are sodium, chloride, and bicarbonate. Calcium and phosphate are present at a supersaturated concentration. Viscosity is due to mucins, proteoglycans with numerous short glycan chains that lubricate the oral cavity, hold a bolus of chewed food together, and reduce bacterial adherence to teeth. Besides mucins, the major proteins secreted in saliva are amylase and proline-rich proteins. The major electrolytes, sodium chloride and sodium bicarbonate, increase with stimulation of salivary flow, but the protein content decreases. All proteins in whole saliva adhere to some extent to... [Pg.208]

In addition to increased calcium and magnesium in the post-C02 water, bicarbonate also increased at Crooks Gap and Bonanza where this analysis was performed (Fig. 5 Table 1). At Bonanza field, bicarbonate increased from an average of 446 ppm... [Pg.489]

Administration of sodium bicarbonate increases the alkalinity of the tubular filtrate therefore acidic drugs, for example aspirin and barbiturates become ionized and cannot diffuse back from the tubules to the plasma. Hence their rate of elimination is increased. This may be useful in the event of an overdose. [Pg.25]

Sodium bicarbonate increased the rate of naproxen absorption, and aluminium hydroxide and magnesium oxide decreased it. Dimeticone did not affect ketoprofen bioavailability. [Pg.140]

Decreased sodium, calcium, pH, and bicarbonate Increased potassium and phosphate... [Pg.193]

Bands derived from monodentate and bidentate bicarbonate species were observed on Ga Oj after introduction of CO. The intensity of the absorbance of the band assigned to monodentate bicarbonate increased with the amount of introduced CO and became saturated after introduction of CO exceeded 2.5 kPa. In contrast, the absorbance of the band derived from bidentate bicarbonate species decreased with the amount of CO introduced and vanished after introduction of CO exceeded 2.5 kPa. The amount of chemisorbed CO gas was consistent with the amount of evolved CO gas, and these reached saturation at a CO equilibrium pressure of around 2.5kPa, as shown in Figure 12.5 this indicates that the chemisorbed CO species involved in the photocatalytic conversion of CO over is the monodentate... [Pg.280]

The water used for wort preparation in a brewery has a great influence on beer quality and character. The salt constituents of water can change the pH of the mash and wort. Bicarbonate ions cause a pH increase, while Ca + and Mg + ions cause a pH decrease. Heating of water which contains bicarbonates increases the alkalinity according to the equation ... [Pg.897]

The effects of liquid and gas flow rates for this process are given by Equation 3-13 using the exponents for liquid-film-controlled systems. For an unpromoted 25 wt % K2CO3 solution at a liquid rate of 40 gpm/ft with a gas capacity factor (Fg) of 0.94 Ib - /ft s, industrial experience indicates that the overall K a values will be approximately one-sixth of the values for the standard C02/Na0H system given in Tables 3-3 through 3-6. These values apply for 20% conversion to bicarbonate in the solvent at a temperature of 235""F. The K a value decreases as the percent conversion to bicarbonate increases at the rate of K a oc 1.207 — 1.08 B, where B is the mol fraction of K2CO3 present as bicarbonate. [Pg.83]
