(Sodium bicarbonate or sodium hydrogen carbonate) is a chemical compound with chemical formula NaHCO3 Fu powder looks as solid white. Have a crystalline structure. But appear in a powder. There is a base. The trade name is foo, powder that is commonly called many names together like benking soda (sda baking) soda bread (bread soda) khukking soda (soda cooking) and biodiesel car refused and soda (bicarbonate of soda)The production process (production)NaHCO3 solution process from preparing the lawe (Solvay process) using the relevant reactions are as follows:1. use carbon dioxide react with caustic soda and sodium carbonate as a product.CO2 + 2 NaOH → Na2CO3 + H2O2. then fill the CO2 to react with sodium carbonate, sodium carbonate, hydrogen will be settling down, foo or powder when there are enough concentration.Na2CO3 + CO2 + H2O → 2 NaHCO3Decomposed when it gets hot (Thermal decomposition) When Fu powder gets hot over 70° C will gradually decay into sodium carbonate (Na2CO3) and carbon dioxide (CO2) degradation reaction will occur as soon as the temperature 250° C. 2 NaHCO3 → Na2CO3 + H2O + CO2 If the sodium carbonate sintering temperature of 1000° C, it will be a product of sodium oxide and carbon dioxide. Na2CO3 → Na2O + CO2 Implementation (Applications) The common is used in cooking, baking, which made this powder to be used as a source for full carbon dioxide by decay. In the process of baking, bakery, causing a gap in a powder mixer is full of various kinds of bakery and leave this mixture by gas-phase CO2 does not occur prior to baking. In addition to adjusting its pool or fish to be neutral because the more excessive chlorine make pool there is too much acid.
