While not exactly correct to do so, I'll write "heat" as a product of the reaction to read: If skin is exposed to any of the solutions, the exposed area should be promptly flushed with cold tap water. Magnesium Toxicity. Magnesium will react with hydrochloric acid, because it is higher in the reactivity series than hydrogen. This is an exothermic reaction, meaning that the forming of the bonds MgCl2 and H2 gives off heat. In this experiment, the rate of the reaction between magnesium ribbon and hydrochloric acid will be increased by adding a higher concentration of hydrochloric acid each time. Well... we didn't get any results so now i have to fake them. The faster the reaction, the shorter the time taken for the effervescence to stop. Then, the magnesium is placed in a glass tube containing hydrochloric acid. In case any acid gets into the eyes, flush the eyes at the eye-wash fountain immediately and call the instructor. It is classified as strongly acidic and can attack the skin over a wide composition range, since the hydrogen chloride completely dissociates in an aqueous solution.. Hydrochloric acid is the simplest chlorine-based acid system containing water. Please wear your safety goggles at all times while anyone is working with chemicals or equipment. I'm going to be frank here. For the reaction of magnesium and hydrochloric acid, determine the number of moles of hydrogen that can be produced from 0.035 g magnesium and 7.0 mL 6.0 M HCl.
