The electrodes in the following electrochemical cell are connected to a voltmeter as shown. The half-cell on the right contains a standard silver-silver chloride electrode (see Exercise 88 ). The half-cell on the left contains a silver electrode immersed in $100.0 \mathrm{mL}$ of $1.00 \times 10^{-3} \mathrm{M} \mathrm{AgNO}_{3}(\mathrm{aq}) .$ A porous plug through which ions can migrate separates the half-cells. (a) What is the initial reading on the voltmeter? (b) What is the voltmeter reading after $10.00 \mathrm{mL}$ of $0.0100 \mathrm{M} \mathrm{K}_{2} \mathrm{CrO}_{4}$ has been added to the half-cell on the left and the mixture has been thoroughly stirred? (c) What is the voltmeter reading after $10.00 \mathrm{mL}$ of $10.0 \mathrm{M} \mathrm{NH}_{3}$ has been added to the half-cell described in part (b) and the mixture has been thoroughly stirred?

So we're given information about electrochemical cell. Since we have no battery driving this, this has to be a galvanic cell. So we have a process where we have a gcl solid with an electron yield silver and florida. And the process hasn't knots of 0.22 to three volts. And we're also given for the reduction of copper metal to solid copper. There's uh not standard cell potential of 0.3419V. And since uh cell potentials are independent of the number of Mosul is Trump's transferred. We can just add these together to find our standard cell potential Which in this case is equivalent to 2.3419 plus .2223. And this is equivalent to 0.5642V. And were given information that the concentration of copper through a solution is one mould and we have self potential mhm equal to 0.895 folds. So since we're under nonstop nonstandard conditions, we're going to have to fire nerds equation. So the sl is equivalent to p not sell minus R. T over N. F. Natural log of cube. And we see that we have to multiple trans transferred So and equals two moles of electrons. And we have to multiply the first equation by a coefficient of two in order for everything to cancel out. So as a result a reaction portion of the concentration of chloride squared divided by the concentration of copper. Mhm. So now we can use all our information basically just substitute into our process here. So we have the so we're trying to here to find the concentration of chloride. So 1.0895 -1642. And we have the R. T. over enough factor. We're taking the temperature to be 298 Children. And as a result of this process, we find that our reaction quotient is equivalent to 1.14 times 10 to the 16th. And since the concentration of copper is one, this is equivalent to the concentration of chloride squared. Mhm. And from this information we can find the concentration of chloride, which is equivalent to the square root of this value. And as a result of finding the square root of this value, we can find that we have a value of one point about 1.0 seven times 10 to the 8th molars. So, and this is our final answer.

Chemistry has there were given a Siris are concentrations. And so our first stop here is calculate the concentration for the copper irons where we have our equilibrium constant. That is K equal to see you and H three for two plus all divided by C u two plus at N H three to the powerful. Because that's a stroke. Geometric coefficient. So we console for see you to Platts. That is 1.6 times 10 to the minus 18. So next we need to add the reaction that is occurring. So we have copper. See you to class. See you with an e note. Value off. Plus no 0.34 faults. Now we have Silva have a G plus a g with an anal value are positive 9.80 volts. So given these values that we have here, we can tell that the electrons will front load from the copper to the silver half, sir. Cause copper has a less positive reduction potential. And so it is able to reduce the silver as copper undergoes oxidation. So, following this, we need to calculate the standard potential of the cell. But we have e is equal to the norm, so subtract not point. Not 591 divided by animals Log Cube where we can rewrite que already as see you two plus at a G well squared. So then this we have in order equal to not 0.46 bolts to attract not 0.591 by the by to log 1.6 times 10 to the minus 18, divided by 1.0 squad so, you know, is equal to not 0.99 folks.

To calculate a cell potential under conditions given, we need to know two things that are not given to us directly. One is the SL standard for the reaction, which we can calculate by looking up the reduction potentials for the 2/2 reactions that comprise this overall reaction. That is 0.46 being a galvanic cell. Then we also need to solve for the copper two plus concentration the copper two plus concentration we can get with the que value that has been given to us and the equation that describes that K value for which we have all the concentrations but copper so we can rearrange that equilibrium constant expression to solve for copper plug in the two concentrations given to us in K belly that's given to us in salt for the copper concentration. Now that we have the copper concentration, we can use the nursed equation to solve for the cell potential. Under the conditions given s l will be called the SL standard, which we calculated up here minus 0.5916 divided by two most of electrons. Log of this is gonna be our copper concentration divided by the silver concentration which was given to us at one Moeller 0.99 volts

So here we have a diagram off the situation. The current density Do the cube J easy for two when activity and elect Strength Sigma and the actual current I is it too Area times current density J If we combine these two equations, we can find the conductivity. What's the block? That's Sigma is equal to the current I for the the area. I'm the electric field strip I over 80 times and the current we know to be nine and piers the area one centimeter times once into me toe is 10 to the minus full square meters electric fields Drink is given to be five times 10 to the minus three volts meter and hence we get in connectivity Sigma one 0.8 times 10 to the power seven. This is in home. So the connectivity is majored in home. Amita. And if you look at our table this activity, it means we can identify the middle to me tungsten
