Runner Posted February 23, 2004 Share Posted February 23, 2004 Can anyone please tell me how fast these reactions will occur. Haven't done the experiments yet, so I'm mystified Zn(s) + CuSO4(aq) ==> ZnSO4(aq) + Cu(s) Zn(s) + Pb(NO3)2 (aq) ==> Zn(NO3)2 + Pb(s) Any help would be much appreciated. Thank you.

YT2095 Posted February 24, 2004 Share Posted February 24, 2004 how "FAST"? it`ll start instantly, but the speed depends on many factors. concentration of sollution, temperature, surface area of your Zn etc... it`s rather diffucult to impossible to calculate in all honesty but it certainly wont Explode Link to comment Share on other sites More sharing options...
Runner Posted February 24, 2004 Author Share Posted February 24, 2004 Thank you for the reply. The reason why I’m asking this is because I have to plan an experiment to suggest that the enthalpy change between a metal and a solution of a salt is related to the relative position of two metals in the reactivity series. Firstly I thought that if the reaction takes too long I should use a temperature –time graph and use a temperature correction method to obtain an accurate result. If the reaction is slower than a neutralisation reaction I could simply just note the maximum temp it reaches. Which one is most sensible If I was going to use about 3.30g of zinc with the solutions being approximately 50cm^3 ? Thank you. Link to comment Share on other sites More sharing options...
