Chemistry Volcano Experiment
Hello All,
Just before the first term of the year ended on 29 Mar, i gave the class a chemistry experiment to prepare for the last lesson. As with all experiments, the students learnt to write a report and along with it have a lot of fun setting up the experiments.
Title: My Volcano Experiment
Aim: To study the rate of reactions
Equipments: As seen in the photos
Procedure: Basically, we kept everything constant and we varied the temperature of the vinegar. We used a fixed quantity of hot, ice cold and ambient vinegar. We used the hair dryer to warm up the vinegar; we used an ice /salt bath to cool the vinegar down to below zero.
Conclusion: The rate of reaction between hot vinegar and sodium carbonate was the fastest, followed by ambient vinegar and cold vinegar. This is because, molecules at high temperature have high kinetic energy that will collide more frequently and at greater speed to produce effective reation.
Here are some amazing photos that the students have taken. I hope that you will find chemistry experiment easy to carry out and fun way to learn!

Hope you have found the experiment easy and fun to do :)
