Interpretation Introduction
(a)
Interpretation:
The anode and the cathode should be labeled and the signs of the electrodes should be indicated.
Concept introduction:
In electrolysis, Anode is where oxidation occurs and indicated by positive sign. Cathode is where the reduction takes place and indicated by a negative sign.
Interpretation Introduction
(b)
Interpretation:
The direction of electron and ion flow should be indicated.
Concept introduction:
Electrons flow from anode towards the cathode. Anode attracts anions and cathode attracts cations.
Interpretation Introduction
(c)
Interpretation:
Balanced equations for the anode, cathode and overall cell reaction.
Concept introduction:
When molten salts are electrolyzed the cation is reduced at the cathode and the anion is oxidized at the anode. When there is a mixture of molten salts, cation with higher reduction potential is reduced at the cathode and the anion with lower reduction potential is oxidized at the anode.
For each scenario below, select the color of the solution using the indicator thymol blue during the titration.
When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] .
At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] .
When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] .
When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color is
The following reaction is run in which the initial conditions include only methane (CH4) at a concentration of0.115 M. Once equilibrium was established, the concentration of acetylene (C2H2) was measured to be 0.035M. What is the value of the equilibrium constant, K?2 CH4 (g) ⇋ C2H2 (g) + 3 H2 (g)
Calculate the equilibrium concentration of carbon dioxide for the following reaction:2 COF2 (g) ⇋ CF4 (g) + CO2 (g) Kc = 2.00 at 10.00 °C. at equilibrium [COF2] = 0.255M; [CF4] = 0.118M
