Uses of Aluminum Ammonium Sulphate

Crystal Growing:

Ammonium alum crystals can be easily grown from a solution of the compound. These crystals are often used in educational settings to demonstrate crystallization processes or as a simple experiment for students to conduct.

pH Buffer:

Ammonium alum can act as a buffer solution, helping to stabilize the pH of certain solutions, particularly in educational or small-scale laboratory experiments.

Protein Precipitation:

It can be used for protein precipitation, particularly in the purification of proteins. Ammonium alum can help precipitate proteins out of solution, aiding in their isolation and purification.

Electrophoresis:

In some cases, aluminum ammonium sulfate can be used in electrophoresis applications, particularly in polyacrylamide gel electrophoresis (PAGE), where it can help to create a stable gel matrix.

Dyeing and Staining:

In histology and cytology laboratories, ammonium alum may be used as a mordant in staining procedures to help fix dyes to tissues or cells.

Microscopy:

Ammonium alum can be used as a mounting medium in microscopy to prepare slides for viewing under a microscope. It helps to preserve the specimen and provide clarity for observation.
