Intro

science lab Intro In Lab #5 nuclear number 23 we entrust be exploring the cycle of pig bed through some chemic chemical reactions. What we are going to do is take a piece of bullshit metallic element put it through a series of reactions that change it¡¦s state of matter and chemical formula, but in the end, we will return it to it¡¦s habitual solid state. The idea of this lab is to try to recover as close to ampere-second% of the copper we started with. Theoretically, this is possible, but for inexperienced college students, retrieving 100% of the copper metal is almost impossible. There are cardinal reactions that the copper will go through. 1. 3Cu(s) + 8HNO3(aq) + O2 „³ 3Cu(NO3)2(aq) + 4H2O(aq) + 2NO2(aq) 2.

3Cu(NO3)2(aq) + 2NaOH(aq) „³ Cu(OH)2(s) + 2NaNO3(aq) 3. Cu(OH)2(s) „³ CuO(s) + H2O(aq) 4. CuO(s) + H2SO4(aq) „³ CuSO4(aq) +H2O(aq) 5. CuSO4(aq) + Zn(s) „³ ZnSO4 + Cu(s) At the end of reaction number five we should deplete close to 100% of the copper we started out with.
