1. Construct the potential-pH (Pourbaix) diagram for zinc using the following reactions and assuming the activity of all dissolved substances (i.e. any metal cations or anions) is 106. Label the stable species in each region. Designate regions as Active (Corrosion), Passive, or Immune. Ranges for potential -2.5 VSHE to +2 VSHE (Y-axis) and for pH -2 to 14 (X-axis) while plotting the results. {1} Zn²++2e−=Zn(s) (E。= -0.764 V vs.SHE) {2} ZnO(s)+2H++2e¯¯=Zn(s)+H₂O (E。=-0.439 V vs.SHE) {3} ZnO2+4H+2e¯=Zn(s)+ 2H2O (E0= +0.441V) {4}Zn²++H20=Zn0+2H+ (equilibrium constant = 3.16 X 10-³) {5} ZnO+H20=ZnO₂²+2H+ (equilibrium constant = 1.58 X 10-30)

Calculate the activity of Al3+ in a solution that is .0547M in Al2(SO4)3.

How can I remeber all these different compounds?

When the element zinc (Zn) is added to hydrochloric acid (HCI), a single replacement reaction occurs. It produces molecular hydrogen (H2) and zinc chloride (ZnCl2). Zn(s)+2 HCI(1) H2(g) + ZnCl2(s) A chemist combines 1.03 grams of zinc with an excess amount of hydrochloric acid in an Erlenmeyer flask. A visible reaction occurs with the formation of bubbles and color change. When a burning wooden splint is inserted into the flask, a distinct popping noise is heard, indicating hydrogen gas was produced. Periodic Table If all of the zinc reacts, what is the total mass of zinc chloride prod should include three significant figures.
