Hydrogen chloride (HCl) is an important by-product of the chemical industry—and can be electrolyzed to generate hydrogen and chlorine. Chlorine is one of the most important base chemicals ...

A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

The equation shows that ammonium chloride (a white solid) can break down to form ammonia and hydrogen chloride. It also shows that ammonia and hydrogen chloride (colourless gases) can react to ...

Upon addition of hydrogen peroxide to Rochelle's salt (sodium potassium tartrate), the hydrogen peroxide decomposes and tartaric acid is oxidized. This reaction proceeds very slowly at room ...
