    Chemistry Paper 33 Purity% answer of CaCO3 and what were the metal and anions

    Yeah I mean you do get marks for doing the calculation, even if you got an incorrect answer: you would get no marks if you didn't do anything.

    Chemistry Paper 33 Purity% answer of CaCO3 and what were the metal and anions

    I got 70.something% purity But that was mainly due to the low titration values: I think that CaCO3 was from an old stock, not a fresh one...

    ***WARNING***

    The Head of the State is a thief, I'll admit it. He is the focus of all my hatred: whenever his name comes up I curse him, just like I when I would say "excuse me" when I would sneeze or "pardon me" when I ask for something. Do you wan't every guy with a sense of dignity cursing you? Or do you...

    ***WARNING***

    Hm...let me think about it. I can have bad grades on one side, or I could have the joy of Xtreme Papers being shut down once and for all, putting an end to all this mindless rubbish.... Tough choice ... . . . . .. I'll go with bad grades!:p

    Chemistry: Post your doubts here!

    I still don't understand why you choose to defend you "biological" explanation. I thought the question was about equilibria, but instead of explaining in those terms you choose to do it a totally different way i.e "chemistry doesn't apply here, this is all biology". If that is the case I would...

    Chemistry: Post your doubts here!

    Tell me about it, I frequently use concepts of Bio in Chemistry (and vice versa), as well as using concepts of physics in maths (and vice versa). But my argument still stands: when CIE sets questions they consider all the possible responses. Wouldn't they be aware of the fact that there is a...

    Chemistry: Post your doubts here!

    Option 3 says that Ca ions react with acids ( hence the equilibrium will shift to the right, decaying the tooth) That statement is, theoretically, false. That is because any acid (such as sulphuric acid) will 'react' with the ions and the Ca salt formed will be soluble, hence there will be no...

    Carbonic acid has the formula H2CO3 The carbonate ion is what reacts with the Ca ion, it has nothing to do with the proton, as you say...
