Conductometric Titration Calculator

The Conductometric Titration Calculator is a scientifically precise, interactive tool that determines the **equivalence point** and **unknown concentration** from conductance vs. volume data. Based on **Kohlrausch’s law of independent ion migration** and **linear regression of pre- and post-equivalence segments**, it automatically detects the intersection of two straight lines. Ideal for **acid-base**, **precipitation**, and **complexometric** titrations in water, soil, and fertilizer analysis. Achieve lab-grade accuracy without manual plotting.

What is Conductometric Titration?

**Conductometric titration** measures solution conductance during titration. Conductance (G = 1/R) depends on ion concentration and mobility:

Where λ = molar ionic conductance, c = concentration. Learn more on Conductometric Titration ScienceDirect.

Scientific Foundation: V-Shaped Plot

Conductance changes linearly before and after equivalence due to ion replacement. The intersection is the **equivalence point**.

• Strong acid + strong base: Decreasing then increasing
• Weak acid + strong base: Decreasing then flat/increasing
• Precipitation: Sharp minimum

Importance of Conductometric Titration

Advantages over indicators:

• No color interference
• Works in turbid/coloured solutions
• High precision (±0.1%)
• Automated endpoint
• Applicable to weak acids/bases

In agriculture, it quantifies **chloride in irrigation water**, **sulfate in fertilizers**, and **acidity in soil extracts** — a focus at Agri Care Hub.

User Guidelines

Steps:

1. Enter titrant concentration and initial analyte volume
2. Paste volume (mL) and conductance (μS/cm) data
3. Click “Calculate Conductometric Titration”
4. View V_eq, concentration, and interactive plot

Use 5–10 points before and after expected endpoint

When and Why to Use

Use when you need to:

• Analyze NaCl in saline soil
• Determine H₂SO₄ in battery acid
• Titrate colored plant extracts
• Teach analytical chemistry
• Validate manual titration

Purpose of the Calculator

To eliminate manual graphing and human error. It applies **least-squares fitting** to two linear segments and computes the intersection with **sub-milliliter precision**.

Example: HCl + NaOH

• 25.0 mL HCl + 0.100 M NaOH
• Data: 0 mL → 800 μS, 10 mL → 200 μS, 30 mL → 600 μS
• V_eq = 20.0 mL → [HCl] = 0.080 M

Applications in Agriculture

Conductometric methods enable:

• Soil salinity mapping
• Fertilizer quality control
• Irrigation water monitoring
• pH-independent acidity
