Non-Chemical Silver Cell details

[AKDan]

From your description of the tests you performed, all indications are that your power supply is working correctly.

In this test you performed, unless the steel ruler and the plyers were touching you will see the volts rise, but no current flow jsut as you noted.

"I clip one end to a stanless stell ruler
the other end to a pair of pliers
This is what happend
-the meter for the volt moved and not the amps"

In this test you performed, it is exactly the same as the first test, with the same results.

"If I test this wthout anything on the clips this is what happens
-I am able to adjust the volts from 0-12
but not the amps"

The way you will get the adjustment in your cell is by simply hooking it up for use and adjusting your power supply voltage to the desired number of volts. As the solution becomes filled with impurity you will see the volts reduce and the current rise.

As the system operates you will simply need to adjust it accordingly. If the amps start going to high, back off the knob, or clean the cell.

when I clipped the 2 leads this is what happend
- When I turned the centre knob the amp meter moved but the volt meter just stayed put.

When you turned the knob and the amps went up, the volts went up also, It was just such a small amount (because of the very low resistance) that it was nearly imperceptible to you.

If I test this wthout anything on the clips this is what happens
-I am able to adjust the volts from 0-12
but not the amps

For any current to flow, you must have a complete circuit. When a plating cell is hooked up between the 2 power supply leads or when you clip the leads to each other, you have a closed circuit. When the leads aren't both hooked to any ONE SINGLE THING, you have an open circuit and no current will flow.

My question is this ¸
How can i get the
1.25 volts measured at the cathode and anode
2.5 amp
Like jims cell

You can't. It would be foolish to want to do it anyway. In a circuit, there is voltage, amperage, and resistance. The resistance is fairly constant in the system. For a constant resistance, when you raise the amps, the volts will decrease - and visa versa. When plating, you normally set the amperage and let the voltage fall where it may - or, visa versa. In your system, you likely have a different system resistance than Jim does. Therefore, when you set it at 1.25 V, the amps will not likely be 2.5 A. But it makes no difference. If you run a silver cell, set the amps and let the volts be whatever the resistance in your system wants them to be.

Hi Chris and Akdan
Thanks for your explanation.
I really appreciate your help

Once the nitric solution becomes unable to refine anymore how can I make is so that I collect the silver
Do I hang a copper in there
Thank You

A great deal depends on what you have in solution. If silver is but a trace of the contained values, you may be better off recovering with HCl or salt. The resulting silver would be much cleaner. Otherwise, if your solution is quite clean, yes, use copper. When that becomes your choice, make sure you have consumed the vast majority of the free nitric, although a trace is actually desirable. Use large pieces of copper, not wire. Wire tends to break up as it is consumed, making it almost impossible to remove when cementation is complete. That defeats the purpose of the operation. By using large pieces, you can fish them out when all the silver is down. The only exception to the use of wire might be if you have a huge amount of silver in solution and you know you'll consume all of the wire before exhausting the silver in solution. When all the wire is gone, you an then add some large pieces to complete recovery.

This is what I do. Not wire wire, but other small pieces of copper. It works very well when you know approximately how much silver is in solution. I also stir the solution every now and then and wait at least a day before I add the large piece of copper.
