K2Cr2O7 is a salt composed of potassium, chromium(VI), and oxygen. It is a crystalline compound with a deep red color. K2Cr2O7 has several interesting properties, including being:
Basic: K2Cr2O7 reacts with acid to form chromium(VI) oxide (Cr2O7^2-) and potassium salts.
Insoluble in water: K2Cr2O7 is insoluble in water, which makes it a useful indicator for the presence of acidity or alkalinity.
A powerful oxidizing agent: K2Cr2O7 is a strong oxidizing agent, capable of oxidizing other substances, such as hydrogen peroxide (H2O2) and metals like copper (Cu).
Examples:
K2Cr2O7 can be used as an indicator in acid-base titrations.
It can be used to test for the presence of chloride ions in a solution.
KMnO4 is a salt composed of potassium, manganese(VII), and oxygen. It is a powerful oxidizing agent with several interesting properties:
