EQUILIBRIUM BETWEEN SODIUM CARBONATE, SODIUM BICARBONATE AND WATER. [SECOND PAPER.]

Interactive Effects of the Carbon Paper, Sodium Bicarbonate and Oral Contraceptive Pills on Morphine Urine Test

Abstract Background and objectives: A major problem for labs. esp. medico legal centers is drug test false positive and negative results. Using carbon paper, sodium bicarbonate or oral contraceptive pills (OCP) are common among addict people to make the results negative. Therefore, we decided to evaluate the effect of carbon paper, sodium bicarbonate or OCP on morphine urine test. Material and ...

A sodium carbonate-bicarbonate buffer for alkaline phosphatases.

For the study of alkaline phosphatase systems a non-phosphate-containing buffer is required. The buffers in common use for the alkaline pH range are ammonia, borate, glytine and veronal. Ammonia and borate have a retarding effect on the rate of ,enzymic hydrolysis of phosphoric esters. Glycine activates phosphatase when present in very low concentrations (0 1-1 mm), but in the concentrations us...

Sodium bicarbonate

Major uses Sodium bicarbonate is a main constituent of baking soda/powder. Baking powder is composed of 30% of sodium bicarbonate, with cornstarch, sodium aluminium sulfate, calcium acid phosphate, and calcium sulfate [1]. Sodium bicarbonate may be an ingredient of folk remedies containing turpentine, castor oil, lemon and sugar. It is also added to mouthwashes and dentifrices to prevent dental...

Sodium bicarbonate revisited.

Sodium-coupled bicarbonate transporters.

Together, the Na(+)-coupled HCO(3)(-) transporters and the AE family of anion exchangers (i.e., Cl-HCO3 exchangers) comprise the bicarbonate transporter (BT) superfamily. Virtually all BTs are important for the regulation of intracellular pH (pH(i)) in cells throughout the body. Specific BTs also play roles in cell-volume regulation, as well as for the transport of salt and/or acid-base equival...
