An electrolytic cell is?

August 3rd, 2010

a battery.
a cell in which the cell reaction is spontaneous.
a cell in which an electric current drives a nonspontaneous reaction.
a cell in which reactants are continuously supplied to the cell.

HELP! A constant current is passed through an electrolytic cell containing molten MgCl2 for 18 hours……..?

August 2nd, 2010

If 4.8 x 10 ^ 5 g of Cl2 are obtained, what is the current in amperes?

I am trying to study for my final, and there are review final questions with no answers. I try to do some , but am not sure if thats the way to do it or if it is the right answer.

Thank You , I really appreciate your time.

Say Electrolytic Injection not HHO generator Brown’s gas

July 30th, 2010


Electrolytic injection is a new and exciting term for HHO, Brown’s Gas, water for fuel, hydrogen injection, and oxyhydrogen fuel cells. Billy Newsom of www.hhokitstore.com promotes this new key term in order to develop a more friendly term to be used in marketing, press releases, and in general terminology. Just as all industries have their specialized jargon terms, we already see many ugly phrases used to describe the systems and the gasses which supplement engine fuels with a mixture of hydrogen and oxygen from the electrolysis of water. But of the many technical terms out there, none of them are suitable for the general public… until now. Electrolytic Injection and electrolytic generators are some of these new phrases. See www.hhokitstore.com Coining the term Electrolytic Injection by Billy Newsom.

Indicate whether it occurs at the cathode or anode, tell if each is voltaic or electrolytic cell.?

July 30th, 2010

(A) For each half-reaction, indicate whether the reaction occurs at the cathode or the anode. Assume it is a voltaic (galvanic) cell.
(1) Sn -> Sn+2 + 2e-
(2) Cu+2 + 2e- -> Cu
(3) Zn -> Zn+2 + 2e-

(B) Indicate whether the item in the list describes a voltaic cell or a electrolytic cell.
(1) measured potential (voltage) is negative
(2) electrons flow from anode to cathode
(3) reaction is spontaneous
(4) in order to proceed as written, an external electrical current must be supplied
(5) cell potential (Ecell) is positive

A steady current of 1.00 amperes is passed through an electrolytic cell AgNO3…?

July 29th, 2010

Question:
A steady current of 1.00 ampere is passed through an electrolytic cell containing a 1 molar solution of AgNO3 and having a silver anode and a platinum cathode until 1.54 grams of silver is deposited.

(a)How long does the current flow to obtain this de¬posit?
(b)What weight of chromium would be deposited in a second cell containing 1–molar chromium(III) ni¬trate and having a chromium anode and a platinum cathode by the same current in the same time as was used in the silver cell?

Is a fuel a Voltaic cell or an Electrolytic cell?

July 28th, 2010

In electrolytic cell, current of 4A is passed thru XCl for 20 min, and made 1.15g of metal X. What is X?

July 28th, 2010

In an electrolytic cell using inert electrodes, a current of 4.00 A is passed through a molten binary salt with the formula XCl for 20.0 minutes.
1.15 g of metal X is produced at the cathode.
What is the metal X?

(a) Li
(b)Na
(c)K
(d)Rb
(e)Cs

I tried to use ne=IT/F with F=9.65×10^4 c/mol, I=4c/s, T=20min=1200s.
Then divided 1.15 g with calculated ne, 4.97×10^-2 mol.
The answer I got was about 23.14 g/mol, and closest was Na with 22.99 g/mol. Did I get correct or did something wrong??

Does an ELECTROLYTIC CAPACITOR store electricy when in an DC circuit only?

July 27th, 2010

I have an HID xenon conversion kit installed in my motorcycle.. I hope to save electricity of my battery by having a capacitor. Does it help conserve electricity? I mean the does the capacitor conserve electricity when i’m using my HID Xenon bulb?

Electrolytic cell (finding time)?

July 27th, 2010

an electrolytic cell is used to plate silver from a silver nitrate solution onto an electrode. How much time (in seconds) is required to deposit 8.0g of silver if the current is kept constant at 5.0 amperes? Assume 100% current efficiency (F=96480C/mole-)

Electrolytic Cell help?

July 26th, 2010

Draw and label an electrolytic cell suitable for electrolysing molten CaCl2. Write down the anode and cathode reactions, and specify the products of the electrolysis.

Would it be possible to obtain calcium metal from the electrolysis of aqueous CaCl2? Explain.


Now this is what I’ve got so far:

(Ca^2) calcium ions migrate towards the negative catjpde/
Ca^2 + 2e- < -> Ca

(Cl2) Chloride ionsmigrate towards the positive anode.
2Cl < -> 2e- + Cl2

The overall cell reaction is
Ca^2 + 2Cl- —> Ca + 2Cl2

But I’m not sure if it’s right, and I don’t know how to answer the second part of the question.

AP Chem free response question about electrolytic cell?(please help)?

July 25th, 2010

In an electrolytic cell, a current of .250 ampere is passed through a solution of a chloride of iron, producing Fe(s) and Cl2(g).

1) Write the equation for the half reaction that occurs at the anode?

2) Write the balanced equation for the overall reaction that occurs in the cell?
