For Teachers

this simulation builder link. This model isn't just a teaching tool—it's a game-changer.

In this blog post, we'll explore the simulation's innovative features and how it can transform your chemistry lessons into an unforgettable learning experience. Let's dive in!

Key Features of the Electrolysis Virtual Lab

1. Dynamic Visualization of Electrolysis Reactions

The simulation offers real-time visualization of electrolysis for various solutions, including:

• Dilute NaCl (Sodium Chloride)

• Concentrated NaCl

Students can observe how ions move towards the anode and cathode, mimicking real-life laboratory conditions. The gaseous products at each electrode (like chlorine gas and hydrogen gas) are shown bubbling dynamically, enhancing conceptual understanding.

2. Customizable Options for Different Electrolytes

With a simple dropdown menu, users can switch between solutions such as:

• Dilute NaCl

• Concentrated NaCl

• Additional electrolytes can be easily added by modifying the source code.

Each option adjusts the reactions displayed and the ionic composition, allowing students to compare and contrast different setups.

3. Accurate Chemical Equations

The simulation dynamically displays the oxidation and reduction half-equations, as well as the overall reaction:

• Anode Reaction (Oxidation): For example, in concentrated NaCl: 2 Cl⁻ (aq) → Cl₂ (g) + 2 e⁻

• Cathode Reaction (Reduction): For example, 2 H⁺ (aq) + 2 e⁻ → H₂ (g)

• The overall equation is clearly shown for easy understanding.

This real-time display ensures students can directly link the observed phenomena with the corresponding chemical processes.

4. Interactive Bubbles that React to Liquid Levels

Bubbles representing gas production dynamically rise through the liquid and disappear when they reach the air-liquid boundary. This unique feature mirrors real laboratory observations, reinforcing key concepts about electrolysis and gas production.

5. State Tracking and Scoring System

SLS ready for use as Interactive Response HTML5 Item The simulation includes built-in logic to track user interactions, ensuring students:

• Only score points when correct options are selected (e.g., "dilute NaCl" or "concentrated NaCl").

• Have a maximum score limit of 2 per session, avoiding repetitive scoring for the same actions.

This feature fosters active participation while preventing exploitation of the scoring system.

6. Seamless User Interface

• "Play" and "Reset" Buttons: Simple controls allow students to start or restart the simulation anytime.

• Dropdown Menu for Solutions: Effortless switching between electrolytes.

• Highlighting Electrodes: Labels such as "Anode" and "Cathode" make it clear which reactions occur where.

7. Real-Time Reaction Logic

The simulation's backend code dynamically checks and processes:

• The movement of positive and negative ions towards the electrodes.

• Gas production and its accumulation in test tubes.

• Reactions based on solution type and electrode polarity.

This ensures an authentic and scientifically accurate simulation.

8. Fully Customizable Code

Built using EJS, the simulation is open-source and highly adaptable. Teachers and developers can:

• Add new electrolytes.

• Modify ion concentrations.

• Adjust the visual appearance to match specific educational needs.

9. Educational Benefits

Bridging Theory and Practice

Traditional textbooks often struggle to connect chemical equations with real-world phenomena. This simulation bridges the gap by visually demonstrating:

• The movement of ions.

• Gas formation.

• Energy flow within the system.

Enhancing Engagement

The interactive nature of the simulation captures students' attention and encourages hands-on learning. Instead of passively reading about electrolysis, they actively explore and manipulate variables.

Promoting Experimentation

Students can "fail safely" in the virtual lab by resetting and trying different electrolytes or observing incorrect setups, fostering a spirit of curiosity and experimentation.

How to Use the Simulation in Your Classroom

1. Demonstrate Electrolysis: Project the simulation during lessons to visually explain electrolysis of dilute and concentrated NaCl.

2. Student Exploration: Assign it as an interactive activity where students predict and observe reactions.

3. Lab Preparation: Use the simulation to prepare students for hands-on experiments, ensuring they understand key concepts beforehand.

Why This Simulation Is a Must-Have for Educators

This EJS-based simulation is not just a tool—it's a transformative learning experience. It makes electrolysis accessible, engaging, and deeply educational. By leveraging the power of interactivity and visualization, educators can inspire a love for chemistry and a deeper understanding of its principles.

Share this simulation with your colleagues, embed it in your teaching, and watch as your students grasp complex concepts with ease.
