Will cold acetone mix with hydrochloride

Acetone is a polar organic solvent, while hydrochloric acid (HCl) is an aqueous solution of hydrogen chloride. When cold acetone is mixed with hydrochloric acid, they do not form a homogeneous solution. Acetone is relatively insoluble in water, and while some interactions may occur, such as protonation of the acetone, the two substances will generally not mix well. If you are experimenting or working with these substances in a chemistry context, ensure you take appropriate safety precautions, such as wearing gloves and goggles, and work in a well-ventilated area. If you need specific guidance or have a specific application in mind, please provide more details.
