pH Indicator Visualizer

A colorful chemistry mini-project to visualize the relationship between pH, solution color, and hydrogen ion concentration.
Built using Python and Matplotlib for Class 11 Chemistry.

---

🧪 Overview

The pH Indicator Visualizer is a simple educational tool designed to help students understand:

• How pH relates to solution color
• How [H⁺] (hydrogen ion concentration) changes across the pH scale
• How acids, bases, and neutral solutions differ visually & numerically

It displays:

• A color block representing the pH value (0 = red, 7 = green, 14 = blue)
• A semilog graph of Hydrogen ion concentration vs pH
• A highlighted marker showing the entered pH value

⚠️ Academic Use Only This project is designed for learning, demonstration, and practical submission purposes. Not intended for chemical analysis or lab instrumentation.

🎨 Features

🔹 Color Representation

Maps pH → RGB color:

• Acidic (0–7) → Red → Yellow → Green
• Neutral (7) → Pure Green
• Basic (7–14) → Green → Cyan → Blue

🔹 Classification

Automatically labels input as:

• Acidic (pH < 7)
• Neutral (pH = 7)
• Basic (pH > 7)

🔹 Scientific Plot

• Smooth curve of 10^(-pH)
• Semilog scale for readability
• Highlights chosen pH value
