What are inert and active electrodes?
Inert electrodes simply serve as electrical conductors and are unchanged by the cell processes. Active electrodes change during the cell reactions. An example of inert electrodes is platinum in the electrolysis of water. The platinum remains unchanged and the water is split into hydrogen and oxygen. An example of active electrodes is in the electrolysis of copper sulfate solution with copper electrodes. The anode copper is converted into copper ions in the solution, and metallic copper builds up on the cathode. The term active electrode is also used in eeg measurement, here as the opposite to passive electrode. Electrodes are the pads attached to the skin to get readings, and active ones don't need a conductive paste to get a good signal.
How can copper be separated from solution of copper compounds?
Usually in a school experiment, you put copper solution into glass. Then you add Positively and negatively charged sticks which are connected with each other and plugged into electricity, which makes pure copper form on the negatively charged stick.
What electrode is more reactive copper or zinc?
Zinc
What can substitute copper or zinc electrode?
That depends entirely upon the application
What are the metal strips called that are placed in the copper compound solution during electrolysis?
electrode
How many volts can a lime produce?
The voltage an electrochemical cell produces does not depend on the electrolyte (e.g. type of fruit), it depends on the two electrodes (e.g. metal strips). The voltage is determined by the relative electronegativities of the two electrodes. For example all cells using a copper electrode and a zinc electrode will produce the same voltage, regardless of the kind of electrolyte they are put into. Another example all cells using a carbon electrode and a zinc electrode produce 1.5 volts, regardless of whether the electrolyte is acidic (the original dry cell batteries), basic (modern alkaline batteries), or neutral (a salt).
How do you use electrode in a sentence?
Inez used a zinc nail and copper penny as electrodes in her science project.

What is the voltage of an electrolytic cell with nickel and copper electrodes?
-0.59 V
Does a cell with copper and zinc electrodes in an acid electrolyte produce voltages?
yes
Does copper need a voltage to produce a current?
Copper can not of itself produce a current. <><><><><> However, resistance, be it copper or some other material, will produce a current if a voltage is applied to it. The rule is Ohm's law: Current = Voltage divided by resistance.
Can C6h8O7 produce electricity?
There are 16 known compounds with that chemical formula, the commonest being citric acid. You could use a solution of citric acid, into which are dipped two electrodes made of different metals, to produce a crude electric cell. Using one electrode made of Copper and another made of Zinc, you could produce a voltage of about 1 volt. Try using a piece of lemon (which contains citric acid), one "copper" coin and one "silver" coin to make a simple electric cell - it works!
Why is Graphite Better Than Copper as an Electrode Material?
Copper or Graphite, which is better suited for use as EDM electrode material, is a topic that has been hotly debated for decades. One of the significant Copper benefits that proponents of the material never failed to point out is the relatively clean workplace you can achieve while doing EDM machining. There are a few additional advantages of copper EDM electrodes as well. However, the final verdict is the one that the popularity of usage points towards, which is undoubtedly Graphite. As much as 70% of all EDM electrodes that you will find globally are EDM Graphite. The number is significantly more significant in the mainland US, where it accounts for a whopping 95% of all electrodes used. The question that will naturally come to your mind is why such a large majority of people choose graphite EDM electrodes over copper EDM electrodes. Let's delve into that. Benefits Of Graphite EDM Electrode The Reduced Costs Associated With Such An Electrode Material While on the surface level, it is true that copper is more affordable than Graphite, but in the case of EDM electrodes, things are not quite simple. Such cost estimates are often made by comparing copper prices to expensive grades of the graphite material. When you factor in the fact that there are indeed many graphite material varieties, some cheaper than copper, the statement does not quite hold ground. Another EDM manufacturing expense that simple estimates of material costs miss out on is the expenses associated with machining the electrode itself. You can save money by choosing graphite EDM electrodes over ones made from copper. The following factors result in such savings: Enhanced cutting speeds Less machining times Electrode production is less time consuming EDM times also increase by using graphite electrodes
How can a banana produce an electricity?
Use two electrodes of dissimilar metal (eg. nickel and copper). Stick them in the bannana. A small voltage will be developed across the two electrodes, due to the mild acid in the bannana. Most fruits (and seeds) will work this way, citrus fruits are better, due to the strength of the acid.
How do you light a light bulb with a lemon?
You would need two sets of electrodes made from two different metals, preferably from opposite ends of the Periodic Table. You put the electrodes out from each other on the top of the lemon. Then you would connect the lemons together in series, alternating the metals you use. For instance, you would connect the copper electrode of one lemon to the zinc electrode on the next lemon. You might need 6-9 lemons, depending on the voltage. You might do better to use a LED instead of a regular bulb, since they draw less current. You can test your lemon cells using a voltmeter to get the polarity and the amount of voltage.

What is the voltage of a pear?
If you are referring to a 'fruit cell' then, in common with all cells, the voltage is determined by the materials from which the electrodes are made -not by the fruit itself. The further apart the metals are on the 'electrochemical series' of elements, the higher the resulting voltage -so, for copper and zinc, the voltage will be about 1.1 V.
