What is the standard reduction potential E?
This is a table with values in volts for the standard reduction potentials of metals to a cathode.
How do you check a reference electrode?
Measure a cyclic voltammogram (CV) of a well-characterized compound, such as ferrocene, whose reduction potential is very well known. If the potential you measure matches the literature value, then your reference electrode is fine. If it does not, then you can determine how far off it is from the difference of where the peaks in the CV should be compared to where you measured them.
Why is it possible to measure an electric potential across the terminals of a dry cell?
Batteries are a voltage storage device that hold a voltage potential until used. By using a volt meter you can find the stored voltage by placing the leads of the meter across the battery's positive and negative terminals.
What do you observe when you put ice into cold water?
You observe the ice melt. You can measure the resulting reduction in the water temperature.
What is the si unit for potential energy difference?
Potential energy is measure in Joules (J). A Joule is a Newton*meter (N*m)
How do scientists measure the standard reduction potential of a half cell?
Pair it with a hydrogen half cell

Would chlorine contribute to conductance in water?
It will. There is an actual sensor used in commercial pools, (ORP sensor: Oxidation Reduction Potential) that measure conductivity, the more chlorine the more conductivity.
What does an angle with a measure of 120 degrees?
An angle with a measure of 120 degrees does nothing. It has no potential to do anything. It just is.An angle with a measure of 120 degrees does nothing. It has no potential to do anything.

Is it possible to have zero potential energy?
Anyone can define a zero of potential energy, from which they are going to measure any other energy elsewhere. Like height, you take your zero to be the soles of your feet, or for a mountain, the sea level, or for a battery cell, one end of it. It may or not be possible to find a place in the universe where there is no lower gravitational potential. Note, usage is generally potential energy=potential x quantity (mass, charge etc).
How do you measure a dropped ball's potential energy?
When a ball is dropped, it no longer has potential energy. Before it drops, you can calculate the potential energy (= mgh); to actually measure this, you would have to measure the force, and multiply that by the distance.
What do elections measure?

How can you measure the business potential in two markets?
with a tape measure :)
What is used to measure potential difference?
A Volt meter is used to measure potential difference (a.k.a. voltage). Potential difference is measured in units called: Volts (V).
What is the voltage between point p and the battery?
The voltage between point p and the battery is not able to measured exactly. You can never measure the absolute electric potential at any point. its just not possible. That is why we talk about difference in potential.
What is the measure of potential energy?
Volts.
