Chemistry Phenomenon – Effervescence in Chemical Reactions

Many of us have observed or heard about EFFERVESCENSE for Chemical Reactions in the school laboratories.

Many chemicals reactions produced Effervescence such as:

• Acid + Metal Carbonates –> Salt + Carbon Dioxide Gas + Water
• Acid + Reactive Metals –> Salt + Hydrogen Gas
• Reactive Metals + Water –> Alkaline Solution + Hydrogen Gas

But how about Effervescence in Our Everyday?Lifes? Effervescence outside the Chemistry Laboratories?

Have you ever wondered?what Effervescense is EVEN if you have not stepped into Chemistry Laboratories before?

I thought the best way to show this to you is by Dissolving A Lozenges!

Check the video out.

PS: Drop me a comment. I would love to hear from you. Of course, i welcome all suggestions on how i can improve my ways of communicating Chemistry.

PPS: If you are looking for more Chemistry Phenomenons, in order to associate it to abstract Chemistry Theories, you can check out CHEMISTRY ARCHIVES on CHEMISTRY PHENOMENON

Many know me as the Ten Year Series book author for JC A-Level H2 Chemistry and O-Level Pure Chemistry. My 19+ years of coaching experience (since 1999) with more than 1500 students from 180+ JCs and Secondary Schools has allowed me to understand the true reasons why students are not able to perform well in Chemistry. Most importantly, my strength lies in using everyday analogies (even grandmothers can understand!) to simplify abstract concepts. Also, my teaching methodology has been designed to be fun, enjoyable and effective for my students.
