Synthetic hydrochloric acid is an aqueous solution of hydrogen chloride, and a typical acidic substance. As an acid that is relatively easy to handle, it is widely used, including in neutralizing and pH adjustment, as raw material for industrial chemicals and foods, as well as surface treatment of metals. Our hydrochloric acid is a synthesized compound made using chlorine and hydrogen derived from brine electrolysis. It contains minimal impurities and can be used with a peace of mind.
