To make hydrochloric acid, you can either dissolve gaseous hydrogen chloride in water using ceramic, glass or tantalum apparatus to avoid corrosion or react salt with concentrated sulfuric acid in a distil flask and collect the excess hydrogen chloride gas that bubbles up.
Another way is to dissolve hydrochloride and water. The water molecules take the hydrogen atom in HCl and put it away from the chlorine atom when hydrogen chloride gas enters the water. This is known as the dissolution process which forms hydrochloric acid.
Here are the steps for making hydrochloric acid using salt and sulfuric acid:
1. Add 100 grams of salt (NaCl) to a flask.
2. Add 200 ml of concentrated sulfuric acid (H2SO4) to the flask.
3. Heat the mixture gently until it starts to boil.
4. Collect the excess hydrogen chloride gas that bubbles up in a separate container.
5. Bubble the gas through water to dissolve it and form hydrochloric acid.
