Chemical activityNernst equation

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

The Nernst equation uses an activity-based reaction quotient; raw concentrations are only approximations under validated conditions.

How to interpret this relation type

The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Nernst equationElectrode potential

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

The Nernst equation adjusts a standard potential for nonstandard activities at equilibrium.

How to interpret this relation type

A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

Nernst equationNernst concentration-cell measurements

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Concentration cells exhibited the activity-dependent electromotive force predicted by the Nernst relation within reversible-cell conditions.

How to interpret this relation type

The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
