This is an inroganic chemistry question, I just need help with number 7 but included everything so you can get background. Please only answer if you can answer it correctly. a) Obtain two 50 mL beakers. Into one beaker add 1.0 M Zn(NO302 and into the other add 1.0 M Cu(NO302. Adjust the liquid depths in each beaker such that they are approximately equal and 1-2 cm deep b) Cut a strip of filter paper that is long enough to...
Can you help explaim and solve how to find delta G along with anything related to half-cells I dont even know where to begin, thank you! WILL probe to the piece of metal foil • Read and record the voltape. Do not forget the NOTE : The The filter paper string should be placed in the welis just prior to measuring the voltage 10. Reverse the probes Record what happens to the sign and switch the meter off NOTE: The...
how would you go about solving this problem via using equations just looking for the equation order i should go about solving this problem In this experiment you will be using the two half reactions Cu?"/Cu and Zn2 /Zn. The standard electrode potential, E°, for these half reactions is +0.34V and-0.76V respectively, so the Nernst Equation for these half reactions is the following Cu ea)+2e - Cus) E - 0.34V 0.0592V Cu2+] 0.0592V Zn 2 Note that solids by definition...
5. What was the purpose of the NaNO3 solution in this experiment? 6. Could a solution of NaCl be used instead of NaNO3? 7. What was the purpose of FeSO4 solution in this experiment? 8. Could a solution of FeCl, be used instead of FeSO4? 9. Could a solution of NaSO4 be used instead of FeSO4? 10. Calculate the standard cell potential for the spontaneous redox reaction between a Pb(s)/Pb(NO3)2(aq) half-cell and a Ag(s)/AgNO3(aq) half-cell. Which metal would be oxidized?...

Prelab Activity: Electrochemical Cells To determine the solubility product of copper(II) carbonate, CuCO3 , a concentration cell as described on pages 71-72 of the lab handout is constructed. The temperature of the Galvanic cell is measured to be 22.5°C, and the cell potential 282 mV (0.282 V). Using this data and Equation 8 in the lab manual, calculate the Ksp for CuCO3 and report your answer with three significant digits. For the Galvanic cell you will construct in PART B,...
Please help! (These are the instructions I had) 1) Preparation of K2[Cu(C2O4)2] 2H2O CuSO4•5H2O + 2K2C2O4•H2O → K2[Cu(C2O4)2]•2H2O + K2SO4 + 5H2O Heat a solution of 2.5g of potassium oxalate monohydrate in 12.5mL of water contained in a 50mL beaker (approx. 90°C). Heat 1.55g of copper sulfate pentahydrate in 3mL of water to about 90°C and add it rapidly, with vigorous stirring to the hot potassium oxalate solution. Set on the bench and allow to cool to room temperature then...
*redox reactions in electeochemical cells* c) Fe/0.1 M FeSO4//0.1 M CuSO4/Cu I soaked a porous cup in tap water for a few minutes and then i let it stand in a 100 ml beaker containing 10ml of 0.1 M FeSO4. I added enough 0.1M CuSO4 to the cup until the two liquid levels were the same height. I inserted a zinc strip into the 0.1 M FeSO4 and a shiny copper strip into the 0.1 M CuSO4. I connected the...
some questions are filled out but still need help woth the remainder of this assignment part B and below needs to be answered. Paragraph Styles . . Electrochemical Cells Objective: Investigate electrochemical potential using electrochemical cells. Information: Electric current is the flow of negatively charged particles. An electrochemical cell is a device that creates an electric current by converting chemical energy into electric current, or vice versa. Voltaic cells are electrochemical cells that produce current spontaneously by converting chemical energy...
