1. One cause of low-level smog is the reaction of ozone, O3, with ethene. The smog contains methanal, CH2O(g), and the equation for its production is shown below.(a) The rate of the reaction doubles when the initial concentration of either O3(g) or C2H4(g) is doubled
Strong Ion Difference.Stewart method.pH is not only determined by the H+ and HCO3- -> other ions in solution influence pH.there are dependent and independent variables determining pH.ATOT (total weak non-volatile acids).SID (net Strong Ion Difference)
To determine the stoichiometry of a chemical reaction.Solution A: 0.5 M sodium hypochlorite NaClO, 55 mL (harmful and corrosive).Solution B: 0.5 M sodium thiosulphate Na2S2O3 in 0.2 M NaOH, 55 mL (irritant).Apparatus (per group).PS foam cup in a 250-mL beaker (x 1) with cotton wool as lagging
Worked solutions to textbook questions 1.Chapter 17 Equilibria involving acids and bases.Calculate the pH of the following solutions.a Step 1 As HNO3 is a monoprotic strong acid, there is one proton to donate fully. Hence the concentration of HNO3 equals the concentration of H3O+

Primary Amines.These are very sensitive to oxidation and generally darken on exposure to air, through autoxidaion at the surface, to give mixtures of complex products. This is particularly true of aromatic amines; a number of products appear to arise
