Please, recommend any source (book, journal, www) on ion pairing
effects in aqueous solutions.
Thanks.

   I understand that one of the common methods for termination of fast
charge is the delta V technique. Kindly clarify the following :
1. Is the voltage to be monitored while charging current is flowing or after
switching it off briefly?

Preamble:

While traveling in rural India recently, my GP NiMH (model GPKB34P)
charger, with its non-universal voltage rating (120v 60 Hz), which i was

I need to find a source of 3V Lithium (it's identical to a commona
photo battery, but I don't have one in front of me to say the model).
The existing battery has small wire leads attached, so it can be
soldered in place.

Help ! I'm confused. Could someone tell me how to
apply the Nernst equation to a FeCl3 standard
solution of 1 g/l (as Fe) to calculate its
equilibrium potential and compare it against

I have some rechargable Lenmar NiMH batteries (2000 mAh, AA) that do not
seem to hold their charge.  Even with no use whatsoever, they seem to be
dead a day or two after a full recharge.  I get only a few minutes of use
from them when I put them in my camera (Nikon Coolpix 2100) ...

I hope some folks in this group have the expertise to help me on this
question.
I am an RV'er that likes to dry camp, and I carry (4) 115AH 12VDC
batteries.  I am an artist and I use some power, OK?

Re: 12v 7ah SLA batteries
I would like to be able to recharge 12v sealed lead acid batteries
in parallel about 6 at a time.
Can anyone tell me if this is feasible?  and what would be the voltage

I've got a battery charger without any microcontroler.
Can anybody tell me at which point the NiMH battery is fully charged?
Something like 1.35 V or Ampere.

I often want to measure the photoelectrochemical character of an
electrode.but i don't know the perfect measurement method .
please recommend a professional book.
thanks !

    Is there anything that will neutralize O2 in water (as sodium
sulfite will) but not actually dissolve in the water?  

I have some questions about plating, and was hoping someone here could help?
When plating Lead Dioxide onto an anode from a lead nitrate bath, I have
read that a small amount of copper nitrate be added to the bath to inhibit
deposition of lead onto the cathode. I believe that the ...

I am a beginner in the conductivity measurement field and I need a hint
for my problem.
I am trying to measure the conductivity of liquids with an instrument
that I built. It has the following specs:

I have a digital camera that can use lithium CRV3 and wonder what
maximum cell voltage it might accept (it ought to accept the maximum
one can get from a new lithium CRV3). I want to know this just to able
to decide if I can safely use a Li-Ion RCRV3. Different brands seems

I have a novel idea of water dissociation by magnetic resonance. I need
help from an individual or a group of electrochemists who would further
develop this idea and possess or have access to laboratory instruments.
I am in Southern California right now.
