On the diagram below sketch the regions where colour has developed and what colour each region is for each test tube. Given that the standard reduction potential for Fe (Fe2*(aq) + 2e→ Fe(s)) is -0.44 V, would any of the metals zinc, lead, or tin, be effective as a sacrificial anode with the given ɔbservations inhibit the corrosion of iron? Justify your answer and also indicate if this agrees iron nail iron + tin iron + zinc iron + aluminium iron + copper Hint: there is no blue colour in the iron + zinc and iron + There's blue colour here. aluminium test tubes (and the pink colour is around the iron nail in these test tubes). Each test tube contains agar gel with phenolphthalein and potassium ferricyanide Use your observations to complete the following table.
