## Nernst Equation

When it comes to electrochemistry, The Nernst equation is an equation that helps to decrease the potential of an electrochemistry reaction to all the standards of the electrode potential, temperature and all the activities that experience the reduction and oxidation.

### Nernst Equation Calculator

The Nernst Equation Calculator calculates the electromagnetic force the cells of the substance that undergoes the reaction and products of the cell reactions. Temperature gives support to impact the Nernst potential that helps to develop across a membrane of two standard principles.

## Nernst Equation at Room Temperature

Nernst Equation Calculator calculates the Nernst equations that are of at room temperature E^{0}. Therefore the standard half-cell reduction potential is E^{0}, z= No of moles that moves to the cells,

Chemical activity for the reduction of the species a_{red} and other chemical activities that help for the oxidation species a_{red} that is given below.

### Rules for Nernst Equation calculator

Firstly you need to read the problem and list out the quantity which is required

Use the formula and calculate

**E=E ^{0}–**

**log**

_{10}

_{ }Whereas E^{0}= standard Half cell reductions potential

Z= No of moles transferred to the cell

a_{red}= chemical Activity for the reductions species

a_{ox}= chemical Activity for the Oxidation species

By substituting the values, we are going to get the best result.

## Issues on Nernst Equation Calculator

### The Emf of the following cells is:

Z_{n}|Z_{n}^{2} (1M) |A_{g}^{+ }(1M)Ag

Find out the reduction potential for this if E^{0}_{Ag}^{+}_{/Ag}= -0.5 V and E^{o}_{Mg}^{2+}_{/Mg}=+1v.

**Step1:**

Given: E^{o}_{Ag}^{+}_{/Ag}=-0.5V

E^{o} _{Mg}^{2+}_{/Mg} = + 1V

E^{o}=E^{o}_{ Ag}^{+}_{/Ag} + E^{o } Mg^{2+}/Mg= 0.5 + 1 = 1.5 V

Chemical Activity for the reduction species (a_{red}) = 1

Chemical Activity for the oxidation species (a_{oxi}) = 1.

**Step 2: **

Reduction Potential is

E = Eo – log_{10 }_{ }

= 1.5 – log10

= 1.5 – 0.02958 × 0.

= 1.5 – 0.

= 1.5 V.

**Answer: ** The Reduction Potential E^{o }= 1.50 V.
