Introduction
Discuss the experiment.
Pre-Requisites:
What are carbonates and bicarbonates
Activity:
The gas bubbling out when carbonates or bicarbonates react with acid., Pick all things in house and see the ingredients in them whether they contain any carbonates or bicarbonates. Now think do they have to react with any acid when you use them?
Real Life Question:
“Which daily used things have metal carbonates and bicarbonates?”
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Carbonate | A salt of the anion CO32?, typically formed by reaction of carbon dioxide with bases |
| Bicarbonate | A salt containing the anion HCO3? |
| Lime water | Lime water is the common name for saturated calcium hydroxide solution.Its chemical formula is Ca(OH)2. |
