Часто задаваемые вопросы

What is Q?

Q is the reaction quotient written for the electrochemical reaction using the chosen thermodynamic activities or approximations.

What does n mean?

n is the number of electrons transferred in the balanced redox reaction.

What is the 25 °C form?

At 298.15 K, E = E° − (0.059159/n) log10 Q.

Does this calculation run on a server?

No. The calculation runs locally in your browser with JavaScript.

Can I use the result directly in laboratory work?

Use it as a calculation aid and verify reagent form, purity, constants, assumptions and your laboratory SOP before operational use.
