    Hydrochloric acid (HCl): Hydrochloric acid is a strong and corrosive acid that is often used as a reagent in laboratories. It is made by dissolving hydrogen chloride in water. 17 Hydrochloric acid is polar substance and has a linear shape with an electronegativity difference of 0.9; it has weak dipole-dipole forces/bonds between its molecules (intermolecular forces) and polar covalent forces/bonds between the chloride and hydrogen ions (Intramolecular forces). (5) HCl has a molar mass of 36.4609
