An experiment, to investigate the reaction times of different amounts of magnesium (Mg) and hydrochloric acid (HCl). Aim To get magnesium and hydrochloric acid to react in 60 seconds Factors * Concentration of acid. * Length of magnesium wire. * Purity of magnesium. * Temperature of room. * Stirring the mixture during experiment. We are going to change the concentration of hydrochloric acid. Prediction Our chosen factor is to change the concentration of hydrochloric acid. We predict that as the concentration of acid decreases, the time of reaction will increase, I think this will happen because as there are less acid particles, the magnesium won't have as many to bump into so the reaction won't be as quick. Apparatus * 100ml beaker * 1 cm magnesium pieces * Pipette * Measuring cylinder * Stop clock * Hydrochloric acid * Water * Goggles * Paper clip Method * Cut the magnesium to pieces of 1cm. * Measure the hydrochloric acid to water concentration. * Clean beaker. * Put the solution of water and acid into the beaker. * Put...
