Electrolysis of Water Model STEM Lab
Product Code : SCL-M-12460
Product Overview:
The Electrolysis of Water Model STEM Lab is a high-precision scientific tool designed to demonstrate the chemical decomposition of water into oxygen and hydrogen gas. Manufactured by Educational Instrument India, this kit provides a visual and quantifiable way to study the 2:1 ratio of gases, helping students grasp fundamental concepts of electrochemistry and stoichiometry. It is a vital component for school chemistry labs, science exhibitions, and STEM-based learning modules.
Key Features & Educational Benefits:
Fundamental Chemistry: Demonstrates the chemical dissociation of $H_2O$ molecules through electrical energy.
Accurate Gas Collection: Features graduated tubes to show the volumetric ratio of Hydrogen to Oxygen.
Green Energy Foundation: Introduces students to the concept of Hydrogen as a clean fuel source.
Durable Construction: Built with corrosion-resistant electrodes and high-quality lab-grade glassware/polymer.
Product Specifications:
Brand: Educational Instrument India
Model Type: STEM Lab Electrolysis Unit (Hofmann Apparatus Style)
Components:
Non-corrosive Carbon or Platinum electrodes.
Transparent graduated collection tubes (50ml capacity).
Sturdy base with integrated power terminals.
Connecting leads with crocodile clips.
Operating Voltage: 6V to 12V DC (Power supply or battery).
Material: Laboratory-grade acrylic/glass and chemical-resistant base.
Compatibility: Aligned with CBSE, ICSE, and international STEM frameworks.
How to Use:
Setup: Place the model on a flat surface and fill the vessel with water.
Electrolyte Addition: Add a small amount of electrolyte (like dilute sulfuric acid or sodium hydroxide) to increase water conductivity.
Power Connection: Connect the terminals to a 6V-12V DC power source.
Observation: Watch as bubbles form at the anode and cathode.
Data Analysis: Observe the graduated tubes to see that twice as much gas is collected at the negative terminal (Hydrogen) compared to the positive terminal (Oxygen).
