Description

Potassium Dichromate AR 500g*

Potassium Dichromate AR (Analytical Reagent grade) is primarily used as a strong oxidizing agent in various chemical reactions, most commonly for the analysis of alcohols through a color change reaction where it turns from orange to green when it oxidizes the alcohol; it’s also used in volumetric analysis due to its stable and non-hygroscopic nature, allowing for precise measurements in “wet tests” of analytical chemistry.
Key points about Potassium Dichromate AR in a lab:
Oxidizing agent:
Its primary function is as an oxidizing agent, meaning it readily accepts electrons from other substances, causing them to be oxidized.
Alcohol detection:
A common application is to test for the presence of alcohols by observing a color change from orange to green when the alcohol is oxidized.
Volumetric analysis:
Due to its stability and predictable reaction, it is used in quantitative analysis (titrations) to determine the concentration of certain substances.
Analytical reagent grade:
“AR” signifies that the potassium dichromate is of high purity and suitable for precise laboratory experiments.
