EXPERIMENT 6 EXTRACTION A. PRELAB ASSIGNMENT B ...

Bicarbonate ion (HCO 3-) is a weak base. It is strong enough to deprotonate the carboxyl group but not the phenol group. Since most ions are soluble in water, deprotonation of these acids is a way of making them water-soluble. Extraction of an ether solution of benzoic acid and naphthalene with aqueous sodium hydroxide will separate these

A process for making sodium bicarbonate from Nahcolite-rich solutions utilizes solubility suppression with addition of salt. Hot water pumped into a Nahcolite-rich formation, which may contain salt (NaCl) and other impurities in excess of 6% by weight, dissolves the Nahcolite (NaHCO 3 ) and salt. The dissolved Nahcolite is brought to the surface as a pregnant brine liquor containing Nahcolite ...

Metabolic acidosis - Osmosis Video Library

Metabolic acidosis is defined as a pathologic process that, when unopposed, increases the concentration of hydrogen ions in the body and reduces the HCO 3-concentration. Not all patients with metabolic acidosis have a low arterial pH (acidemia), the pH and hydrogen ion concentration also depend upon the coexistence of other acid-base disorders.
