Question
For each of the questions below, indicate whether or not therstated reaction will occur. If the reaction will occur, complete the table that follows. Wi hot, leave the table blank. General information for the questions 6, 7, and 8: . Complete the chart for each reaction as needed and answer any questions . Use your periodic table and activity series where applicable. Use the following along with your general knowledge of reactions to predict the observations if the reaction was completed in an actual laboratory setting. Solutions containing the zinc ion, Zn2, the tin(II) ion, Sn2*, the magnesium ion, Mg?", lead(II) ion, Pb2+, and the aluminum ion, Al3, are all clear. Solutions of HCI(aq) are clear Solutions of the cobalt (II) ion, Co+, are pink. Solutions containing the iron(II) ion, Fe2*, are green. Finely divided copper and iron may look brown or black. .Explanation / Answer
Zn(s) + Fe(NO3)2 (aq) ------------------> Zn(NO3)2 (aq) + Fe(s) this reaction will occur
Zn(s) + Fe^+2(aq) +2(NO3)^- (aq) ------------------> Zn^2+ (aq) +2(NO3)^- (aq) + Fe(s)
Zn(s) + Fe^2+ (aq)-----------------------> Zn^2+ (aq) + Fe(s)
oxidation sate of elements on reactant sides Zn = 0 , N = +5
Fe = +2 , O = -2
oxidation sate of elements on products sides Zn = +2 , N = +5
Fe = 0 , O = -2
Zn is oxidised because of Zn oxidation number increases from 0 to +2
Fe is reduced becuse of Fe oxidation number decreases from +2 to 0
Element oxidized Zn
Element reduced Fe
oxidising agent Fe
reducing agent Zn
