However, pennies made after 1982 have a zinc core with copper plating and that plating may be porous so the liquid can react with the zinc. It is quite ductile and malleable at temperatures ranging from 100-150 °С. Aluminum and zinc do not react with concentrated nitric acid since a thick, hard to dissolve oxidation layer builds (passive oxidation) that protects the metal against further assaults. Tin reacts with dilute acids slower than many other metals and heat is often required to speed up the reaction. eg NaOH + Zn ---> Na2ZnO2 + H2. (HT) Calculate the gradient of a tangent to the curve on these graphs as a measure of rate of reaction at a specific time. A metal's ability to react with HCl depends upon the metal's so-called activity, where metals with high activity react with HCl.
