A chemist designs a galvanic cell that uses these two half-reactions: half-reaction Cl2(g)+2e ->>> 2 Cl (aq) Cro(aq)+4 H₂O()+3e → Cr(OH)3(s)+5 OH (aq) Answer the following questions about this cell. standard reduction potential Ed = +1.359 V red 0 E=-0.13 V red Write a balanced equation for the half-reaction that happens at the cathode. Write a balanced equation for the half-reaction that happens at the anode. Write a balanced equation for the overall reaction that powers the cell. Be sure the reaction is spontaneous as written. ☐ ☐ Do you have Yes

Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. relative pH of 0.1 M aqueous solution species H20 4 H,PO4 HNO, (Choose one) NO2 7 OH (Choose one) HF (Choose one) ▼
