re: HSC Chemistry Marathon Archive I was doing a trial paper and then when I reached the end I realised that I didn't have any solutions...... Due to this, can someone please do the following question(s)? Not too confident with my answers and reasoning. Thanks!

re: HSC Chemistry Marathon Archive Industrial Chem Q. Describe and identify the hazards associated with the transport of sulfuric acid (2-3 marks)

re: HSC Chemistry Marathon Archive Quick question, how would you draw a flow-chart to acceptable HSC chemistry standards? I know obviously to use a ruler and pencil and such, but any other specifications? e.g. separate shapes to distinguish added chemicals to processes? acceptable to have...

Oh wait, sorry I missed the point. Point 1 is not a question (I'm thinking) - it's asking you to perform the titration. Then Q2 is where the calculation of the unknown concentration (in this case HCl) comes in. Haha sorry for the mix up

Depends on what the 'solution' Q2 is referring to, i.e. did you for some reason dilute the given solution of HCl before performing the titration? You used methyl orange because the titration was between: strong acid (HCl) and a weak base (Na2CO3) thus an acidic salt was produced from the...
