NaCl is fairly soluble in water, and sulfuric acid is very soluble in water, and both are very much ionized when dissolved in water. You have a solution of ions. (I really should check on the solubility of sodium sulfate just to be more thorough and correct in my comment).Titan97 said:Its given in my book that Sulphuric acid displaces more volatile acid from Metal salts like NaCl.
That is, NaCl + H2SO4→ HCl + Na2SO4
What does valtility have to do with such reactions?
Or Should I just accept it as a fact?
Yes. "Pure?" Depends.Titan97 said:hence it does not come out with HCl gas
The reaction between a metal salt and sulphuric acid is a double displacement reaction in which the metal cation of the salt replaces the hydrogen ion of the acid to form a metal sulphate and water.
The products of the reaction between a metal salt and sulphuric acid are a metal sulphate and water. The metal sulphate is a salt that is soluble in water.
The rate of reaction between a metal salt and sulphuric acid can be affected by factors such as concentration of the reactants, temperature, surface area of the reactants, and the presence of a catalyst.
No, not all metal salts can be used in the reaction with sulphuric acid. Only metals that are more reactive than hydrogen, such as sodium, potassium, and calcium, can react with sulphuric acid to form a metal sulphate.
If an excess of sulphuric acid is used in the reaction with a metal salt, it will not change the products of the reaction. However, it may result in an acidic solution and can be dangerous if handled improperly.
