Sodium bicarbonate or sodium carbonate acid is a chemical compound has the formula NaHCO3.
Sodium bicarbonate white crystalline powder, soluble in water, and insoluble in alcohol, and when it is heated in the dry community or in liquids, it gradually turns into sodium carbonate.
Sodium bicarbonate are fixed in dry air, but disintegrate slowly in moist air, so should be kept in airtight containers, in a cool, dry
When calibration mixture of sodium carbonate and sodium bicarbonate with hydrochloric acid using Ph.Ph Guide, the volume of acid-reactive carbonate equivalent to half. When the calibration mixture in evidence M.O van acid reacts with carbonate bicarbonate and all
n the process calibrator needs to chemical reagent chromatic indicates the end of the interaction, but not included in the interaction. Mostly visual indicator is used based Itagier color when the reaction is complete. Among the reagents used in the calibration simple phenol Vtalin (Phenolphthalein) which symbolizes him as chemical C20H14O4 which turns from colorless to pink when they are accessed or infringement of "value" certain pH (about 8.3). There is also another type of reagents which methyl orange (Methyl orange), a detector turns red in acidic media and yellow in the middle baseband.
