Description
Subtract a supplied liquid-junction offset from a recorded potential.
Electrochemical quantities require explicit electrode references, current sign, area definition and time basis. Geometric area differs from active-area conventions, charge differs from charge equivalents, and a logarithmic current coordinate needs a same-unit reference magnitude. Local sign changes and coordinate terms do not fit kinetics or establish a valid experiment.
Subtract a supplied liquid-junction offset from a recorded potential.
When to use this tool
Use Electrode Potential Liquid Junction Offset when you already have recordedPotential, suppliedJunctionOffset and need to subtract a supplied liquid-junction offset from a recorded potential.
How to use the tool and how it works
- Enter recordedPotential, suppliedJunctionOffset. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read correctedPotential. Use the output convention below.
Return recordedPotential-suppliedJunctionOffset.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recordedPotential | Recorded Potential | Required. Finite number. |
| suppliedJunctionOffset | Supplied Junction Offset | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| correctedPotential | Corrected Potential | Required. Finite number. |

}Limitations and assumptions
- Units and reference must agree. No junction offset, reference-electrode conversion, uncertainty or electrochemical correction is estimated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Inspect calibrated instrument records, reference-electrode details, area definitions and the complete experiment before interpreting results. Use the full electrochemical model and verified operating conditions when a local current, charge, sweep or impedance-representation term cannot answer the scientific question.
