Does The Number of Drops of Catalyst Effect The Rate Of Reaction Candidate Name: Ben Dodds Candidate Number: 7158 School: Oundle School Completion Date: Introduction We are studying the reaction between zinc and sulphuric acid, the reaction is catalysed by copper sulphate and this experiment is to test whether the amount of drops effect the rate of reaction. Word Equation Zinc(s) + Sulphuric acid(aq) --> Hydrogen(g) + Zinc Sulphate(aq) Symbol Equation Zn + H2SO4 --> H + ZnSO4 This reaction is catalysed by Copper sulphate (CuSO4) Ionic Equation - Cancel Spectator ion (SO42-) Zn + 2H+ --> Zn2+ + H2 For this reaction to work there must be hard collisions between the zinc and the hydrogen ions (acidity ion) from the acid, The faster the harder and the more often the collisions happen so I predict the more catalyst the faster the reaction. Planning Safety * Sulphuric acid at 2M is a corrosive substance but diluted to 1M it is an Irritant, so wear a Lab...
