Expert Answer
The chemical formula HCl is the same for both hydrogen chloride and hydrochloric acid.
The difference is in their physical state, if HCl is a gas then it called as a hydrogen chloride gas, and if it is in the aqueous solution then it is known as a hydrochloric acid.
In terms of mass percentage concentrated hydrochloric acid is 37% HCl in water which means in the 100ml of flask, there is 37ml HCl and remaining is water, such solution is known as concentrated HCl.
