The question, scope, and sources behind this Registry record.
The standard potential of the reference hydrogen electrode is fixed at zero by electrochemical convention.
Set the standard potential of the H⁺/H₂ reference electrode under standard-state conditions.
The standard potential of the reference hydrogen electrode is fixed at zero by electrochemical convention.
standard electrode potential — Standard hydrogen electrode potentialChange a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
Current frontiers derived from accepted Claims.
The accepted equality closes this optimization result.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.

The frontier as it changed over time.
Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
