Zinc sulfate, lab grade, granular - 500g

46878

Zinc sulfate, lab grade, granular is commonly used in classroom settings for chemistry experiments and to illustrate various scientific concepts due to its solubility and reactivity. Some of the typical applications include:

Precipitation Reactions: Zinc sulfate is used to demonstrate precipitation reactions when mixed with other compounds. For example, when combined with sodium carbonate, it forms zinc carbonate, a white precipitate. This can be used to illustrate the principles of solubility, ionic reactions, and compound formation.
Galvanic Cells and Electrochemistry: Zinc sulfate is frequently used in electrochemical cells (such as Daniell cells) to study the behavior of zinc as an electrode and to teach concepts of oxidation and reduction, electrode potentials, and electron flow in galvanic cells.
Testing for Anions: It can be used as a reagent in testing for the presence of specific anions in solutions. For instance, in analytical chemistry, zinc sulfate might be utilized in qualitative tests to help identify sulfide ions through the formation of a white precipitate (zinc sulfide).
Growth Medium for Biological Studies: In biology and environmental science classes, zinc sulfate is sometimes used as a trace element in preparing growth media for certain plants or algae to study the effects of zinc on growth and development.
Illustrating Properties of Transition Metals: Zinc is often grouped with other transition metals to compare chemical properties, such as reactivity with acids and the formation of complex ions in solution.

Safety precautions should be observed when handling zinc sulfate, as it can be harmful if ingested or inhaled in powder form. Proper protective equipment, such as gloves and safety goggles, is recommended during use.
