Alkali ash is impure sodium carbonate, and its composition is different because its manufacturing method and source Bu are the same. It may contain sodium chloride, sodium sulfate, sodium hydroxide, etc.
Reaction Equation 2 NaOH+CO2 = Na2CO3+H20H20+Cao = Ca (OH) 2ca (OH) 2+CO2 = CaCO3 Jian The main components of lime are calcium oxide and sodium hydroxide, calcium oxide is mainly used to absorb water vapor, and sodium hydroxide is mainly used to absorb carbon dioxide.
