Chemical kinetics experiments can then be carried out in a pump–probe fashion, using a laser to initiate the reaction (for example, by preparing one of the reagents by photolysis of a precursor), followed by observation of that same species (for example, by laser-induced fluorescence) after a known time delay.
The golden rain experiment involves two soluble ionic compounds, potassium iodide (KI) and lead(II) nitrate (Pb(NO 3) 2). They are initially dissolved in separate water solutions, which are each colorless.
Virtual Labs enable the students to learn at their own pace and enthuse them to conduct experiments. Virtual Labs also provide a complete learning management system where the students can avail various tools for learning, including additional web resources, video lectures, animated demonstration, and self-evaluation.
The frozen bubble experiment Seemingly magical videos of frozen bubbles also routinely appear online demonstrating how a normally ethereal soap bubble hardens into a lacy globe when the ...
For example, one experiment generated toxic chlorine gas, and another used carbon tetrachloride, a potent hepatotoxin. [ 1 ] The book was also believed to be a source of inspiration to David Hahn , nicknamed "the Radioactive Boy Scout" by the media, who attempted to construct a nuclear reactor in his mother's shed, [ 2 ] although the book does ...
Sodium bicarbonate rockets are often used in science classes to demonstrate principles of chemistry and physics. In the experiment, a film canister is filled with water, an effervescent tablet (commonly Alka-Seltzer) is added and the canister tightly sealed.
This experiment is a classic chemistry demonstration that can be used in laboratory courses as a general chemistry experiment to study chemical kinetics and reaction mechanism. [2] The reaction also works with other reducing agents besides glucose [ 3 ] and other redox indicator dyes besides methylene blue.
