Few basic questions about ionic bonding and batteries (lead)
I've got a few very very basic questions about ionic bonds and their role in batteries.
My assumptions (correct me if I'm wrong):
Ionic bonds occur between a metal and a non-metal (the non-metal ...

Trends in conductivity in groups 1 and 2
I have read that the trend for conductivity in groups 1 and 2 is a decrease down the groups (generally). Apparently this is because the atoms of each element get larger, so while the number of ...

How do I increase the amount of electrons transferred in a battery?
I made a simple battery with $\ce{Al}$ as anode electrode with $\pu{0.7 M}$ aluminum sulfate electrolyte. Platinum is my cathode electrode with $\pu{2 x 10^-4 M}$ $\ce{KOH}$ solution. I am generating $...

questions about half cell of Daniell cell
My questions are as follows:
For the Daniell cell, we assume that ZnSO4 and CuSO4 are 1M aqueous solutions. What if we use pure molten ZnSO4 and CuSO4 instead?
Assume that we prepare an isolated half-...

Reduction of potassium ion and hydrogen ion
I am studying a galvanic cell, and the cathode uses potassium hydroxide as its electrolyte. I am getting confused as to what gets reduced when electrons come from the anode.
I believe it would be the ...
