Investigation of acid and magnesium This investigation is to study the reaction kinetics and find out evidence about the mechanism between the reaction of acid and magnesium. It can be done by finding out the rate, order, activation energy and enthalpy change of the reaction. Acid What is an acid? Definition: an Arrhenius acid is a compound containing hydrogen which will form hydrogen ions in water. What is a strong acid? Acids that donate their acidic protons almost completely to water are classified as strong acids; acids that interact very little with water are classified weak acids. Ref, 'Nuffield Chemistry Students' Book' Ionic equation for acid and Mg: 2H+(aq) + Mg(s) --> H2(g) + Mg2+(aq) Rate equation and order of reaction Reactants are converted to products during a reaction and the rate of reaction is a measure of how fast the reaction is. It is an indication of how much reactants are converted into product...
