Explanation: The ideal environmental conditions for a reaction, such as temperature, pressure, catalysts, and solvent. Catalysts are substances that speed up the pace (velocity) of a chemical reaction without being consumed or becoming part of the end product. Catalysts have no effect on equilibrium situations.
NaCl crystals reacts with concentrated H2SO4, then heated, absorb water to obtain the hydrochloric acid solution
In a full sentence, you can also say H2SO4 (sulfuric acid) reacts with NaCl (sodium chloride) and produce HCl (hydrogen chloride) and Na2SO4 (sodium sulfate)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance Na2SO4 (sodium sulfate), appearing at the end of the reaction.
Or if any of the following reactant substances NaCl (sodium chloride), disappearing
Method of preparing hydrogen chloride gas in laboratories
sulfuric acid10FeO + 18H2SO4 + 2KMnO4 → 5Fe2(SO4)3 + 18H2O + 2MnSO4 + K2SO4 H2SO4 + Na2SO3 → H2O + Na2SO4 + SO2 Cu + 2H2SO4 → 2H2O + SO2 + CuSO4 View all equations with H2SO4 as reactant
sodium chloride2H2O + 2NaCl → Cl2 + H2 + 2NaOH AgNO3 + NaCl → AgCl + NaNO3 2NaCl → Cl2 + 2Na View all equations with NaCl as reactant
sodium chlorideCl2 + 2Na → 2NaCl HCl + NaOH → H2O + NaCl 2HCl + Na2CO3 → H2O + 2NaCl + CO2 View all equations with NaCl as product
