Investigation on the effect of a factor on the rate of a reaction Aim: To investigate the effect of changing concentration of a reactant, on the rate of reaction to make Epsom salts. Equation of reaction: Magnesium + Sulphuric acid Magnesium Sulphate + Hydrogen Mg(S) + H2SO4 (aq) MgSO4 (aq) + H2 (g) Epsom salts are Mg2+ and SO42- ions bonded together. They can be used in sea salts and bath salts; they can also be used in hairsprays and body/face scrubs or washes etc. One way to produce Epsom salts is by reacting magnesium with sulphuric acid, when these are reacted Magnesium sulphate (Epsom Salt) and Hydrogen (gas) is made. To solve this investigation, from my experiment, I could measure the amount of salt that is produced from each concentration of acid. However, this may prove to be very difficult. Separating the salt from solution would have to be done over a long period of...
