3. write a report on the use of zinc as a “sacrificial anode” to minimise the corrosion of iron and steel such as on ships. Use the standard electrode potentials given in question 2 above to predict the cell emf and overall equation for the reaction that would occur in standard conditions between zinc and iron. With ocean-going ships, however, what is the solution in which the two metals are immersed? Is this solution always at an exact concentration of 1 mol dm-3? And in what ways does this real-life situation differ from the standard condition of 25oC / 298K Picture of question 2 is also given

10.11/ A 1.5-kg specimen of a 90 wt% Pb-10 wt% Sn alloy is heated to 250°C (480°F), at which temperature it is entirely an a-phase solid solution . The alloy is to be melted to the extent that 50% of the speci- men is liquid, the remainder being the a phase. This may be accomplished either by heating the alloy or changing its composi- tion while holding the temperature con- stant. (a) To what temperature must the speci- men be heated?
