Organic Chemistry : 3 reactions of alkanes SUMMARY
This week post is about Organic Chemistry : 3 reactions of alkanes SUMMARY. First reaction Combustion: Complete Combustion: In the presence of excess oxygen, alkanes burn to produce carbon dioxide (CO₂) and water (H₂O). This is a highly exothermic reaction, releasing a large amount of heat. Examples of complete combustion include the burning of methane…

Chemistry Notes: Titration pH graphs and types of indicators
This post is on Chemistry Notes on Titration pH graphs and types of indicators. Titration pH Curve: Before the End Point: The pH remains high.H⁺ ions added will neutralise OH⁻ ions.The concentration of OH⁻ ions decreases. At the End Point: A single drop causes a sharp change in pH, resulting in a colour change.Just enough…
