I found the correct boiling point, 53 degrees Celsius, but i can’t find another site that gives a melting point that matches up with this boiling point. I hope that makes sense, anyway, any help is appreciated.
Hydrochloric acid is a solution of hydrogen chloride in water – a solute does not decrease the boiling point of a solution compared to the pure solvent, but raises it, so your “correct” boiling point is definitely wrong, as it is lower than the 100°C standard boiling temperature of pure water; google “colligative effects” or “boiling point elevation” if you want to learn more. Similarily, the melting point of hydrochloric acid would be somewhat below 0°C at standard pressure, again a colligative effect, known as freezing point depression. The size of freezing point depression and boiling point elevation depend on the solute concentration.
Hydrogen chloride, on the other hand, is a gas at room temperature, so again your source must be wrong. The data on any compound given on Wikipedia is usually quite reliable. The page for HCl tells me the melting point is -112°C and the boiling point is -85°C, which seems a lot more reasonable to me…

what is the melting point of hydrochloric acid?

Hcl Melting Point
I don’t think it will a clear one. This is a solution (a mixture). As you get to the freezing point the concentration will change, as will the freezing point
*The HCL melting point is -112 degrees Celsius
*The HCL boiling point is -85 degrees Celsius
