Discussion. Magnesium reacts with hydrochloric acid according to the equation: Mg (s) + 2 HCl (aq MgCl 2 (aq) + H 2 (g) This demonstration can be used to illustrate the characteristic reaction of metals with acid, a single replacement reaction, or to demonstrate the generation of hydrogen gas.lace the Petri dish on the overhead projector. Pour hydrochloric acid into the Petri dish to a depth of about 5mm. Turn on the projector and focus it. Using forceps, place the magnesium ribbon into the Petri dish.
Citric acid is commonly used by the fresh-cut produce industry to control pH of chlorine solution for optimized effectiveness. Our results clearly demonstrated that chlorine readily reacted with citric acid and produced high levels of trichloromethane.ur results also demonstrated that citric acid reacted with chlorine and contributed to the formation of high levels of trichloromethane in wash water. To lower the formation of trichloromethane in water, citric acid may be replaced with other pH adjustors such as phosphate.
