What is the pH of SHE?

In SHE, the pH of acid solution should be 0. Here, the Standard Hydrogen Electrodes (SHE) could usually uses 1 M of HCL for the provided acid. It can be represented as, The pH of this 1 M HCl equals 0. Thus, the pH of the acidic solution in SHE will be zero.

What is the pH of acid solution?

The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.

What is the pH of a standard hydrogen electrode solution?

-1
We already know that the standard electrode potential of a hydrogen electrode is equal to zero. In the given question, the electrode potential of hydrogen is equal to \[0.059V\]. Thus, the pH at which the potential of hydrogen electrode will be \[0.059V\] is -1.

Which solution is used in SHE?

SHE is composed of a 1.0 M H+(aq) solution containing a square piece of platinized platinum (connected to a platinum wire where electrons can be exchanged) inside a tube.

What is SHE in chemistry class 12?

A Standard Hydrogen Electrode (SHE) is an electrode that scientists use for reference on all half-cell potential reactions. The value of the standard electrode potential is zero, which forms the basis one needs to calculate cell potentials using different electrodes or different concentrations.

What is a pH of a solution?

The pH of a solution is a measure of hydrogen (H+) ion concentration, which is, in turn, a measure of acidity. Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions: (5.17), in pure water, [H+] and [OH−] are in equal concentrations: [ H + ] = [ OH − ] = 10 − 7 moles/L .

What does SHE chemistry mean?

From Wikipedia, the free encyclopedia. The standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials.
