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.
In a full sentence, you can also say HCl (hydrogen chloride) reacts with Na2S2O4 () and produce NaCl (sodium chloride) and H2S2O4 (Thiosulphuric acid; Hyposulfurous acid; Dithionous acid; Thiosulfate; Hyposulfite)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance H2S2O4 (Thiosulphuric acid; Hyposulfurous acid; Dithionous acid; Thiosulfate; Hyposulfite), appearing at the end of the reaction.
Or if any of the following reactant substances Na2S2O4, disappearing
We no further information about this chemical reactions.
