Product Description
RICCA CHEMICAL RDCS0390-500B1 - RICCA SODIUM CARBONATE - SODIUM CARBONATE IS USED AS A BASIMETRIC STANDARD BUT IT IS NOT A VERY GOOD PRIMARY STANDARD SINCE IT IS DIFFICULT TO DRY, IS HYGROSCOPIC, AND HAS A RELATIVELY LOW EQUIVALENT WEIGHT. FOR THESE REASONS, TRIS(HYDROXYMETHYL)AMINOMETHANE HAS LARGELY REPLACED IT AS A BASIMETRIC STANDARD. SODIUM CARBONATE IS A DIEQUIVALENT BASE AND IT CAN BE ASSAYED BY TITRATION WITH A STANDARD STRONG ACID TO THE FIRST EQUIVALENCE POINT (PH 8.3) USING PHENOLPHTHALEIN INDICATOR, OR TO THE SECOND EQUIVALENCE POINT (PH 3.7) USING METHYL ORANGE INDICATOR. - EQUAL TO C998V24-EA
