Calcium carbonate does not react with sodium hydroxide. Sodium hydroxide is a strong alkali, while calcium carbonate is a weak alkali salt. Moreover, calcium carbonate is insoluble, will not hydrolyze into hydrogen ions, and cannot react with hydroxyl radicals. CaCO3 and NaOH cannot react because in the reaction of double decomposition, the condition that salt+base=new salt+new base is that the reactants are soluble, and there are precipitates or hard ionized substances after the reaction.
Calcium carbonate is an inorganic compound, commonly known as limestone, limestone, stone powder, marble, calcite, which is a compound with the chemical formula of CaCO? Neutral, basically insoluble in water, soluble in acid. It is a common material on the earth and exists in aragonite, calcite, chalk, limestone, marble, limestone and other rocks.
