Chemistry Investigation Junaid Umar 11.2 Reaction Rates Planning stage Aim To investigate how the temperture of hydrochloric acid affects the reaction between magnesium Magnesium+ Hydrochloric acid ? Magnesium chloride + hydrogen Hypostasis Before starting the investigation, I decided to do some research about magnesium and hydrochloric acid. Magnesium is a light, shiny grey metallic element, symbol Mg, atomic number 12, found in group two in the periodic table. It is quite reactive giving vigorous reactions towards acids. It is one of the alkaline earth metals, and the lightest of the commonly used metals. It is used in alloys, flash photography, flares, fireworks and flash bulbs because it burns vigorously in air with a bright white light. Magnesium reacts with steam to release hydrogen and it also burns in carbon dioxide gas. Hydrochloric acid, HCl, is a solution of hydrogen chloride (a colourless acidic gas) in water. The concentrated acid is about 35% hydrogen chloride and is corrosive....
