1.	You want to store a freshly made solution of copper sulphate. You have 4 options with you. Which of these is preferable to ensure that the solution remains intact? Reduction potentials: Zn2+/Zn= −0.76 Mg2+/Mg= −2.37 Cu2+/Cu= 0.34 Ag+/Ag= 0.8 Sn2+/Sn= 0.16
Answer» You want to store a freshly made solution of copper sulphate. You have 4 options with you. Which of these is preferable to ensure that the solution remains intact? Reduction potentials: $Z n^{2 +} / Z n = - 0.76$ $M g^{2 +} / M g = - 2.37$ $C u^{2 +} / C u = 0.34$ $A g^{+} / A g = 0.8$ $S n^{2 +} / S n = 0.16$
