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.
Natri hiroxide is produced by electrolyte of saturated NaCl. Electrolyte tank has a diaphragm between cathode and anode. They can collect hydrogen gas in the cathode, chlorine in the anode, and NaOH in the tank.

Drop a few drops of silver nitrate solution into a test tube with 1ml of sodium chloride solution
So two salt solutions can react with each other to create two new salts

NaCl crystals reacts with concentrated H2SO4, then heated, absorb water to obtain the hydrochloric acid solution
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance NaHSO4, appearing at the end of the reaction.
Or if any of the following reactant substances NaCl (sodium chloride), disappearing
