About this document
Notes No-7 by indiversingh271 is a document available to read on EtoBox.
The document describes tests for identifying carbon dioxide (CO₂) using limewater and burning magnesium ribbon. Passing CO₂ through limewater turns it milky due to the formation of calcium carbonate, while excess CO₂ makes it clear again by forming soluble calcium bicarbonate. Additionally, burning magnesium in CO₂ produces magnesium oxide and carbon, with black carbon particles forming in the process.
