Silver nitrate solution (0.1 normal) is used in classrooms for various chemistry experiments, particularly for demonstrating precipitation reactions and studying properties of silver ions. It is commonly used in:
-
Precipitation Reactions: When silver nitrate is mixed with solutions containing chloride ions (e.g., sodium chloride), it forms a white precipitate of silver chloride. This reaction is useful for teaching concepts like solubility rules and ionic equations.
-
Halide Testing: It can be used to identify halides (chloride, bromide, and iodide ions) in solutions, as each halide forms a distinct precipitate color (white, cream, or yellow) with silver nitrate.
-
Titration Experiments: In analytical chemistry, a 0.1N silver nitrate solution can be used for Argentometric titrations, such as the Mohr method, to determine the concentration of chloride in a sample.
-
Biological Staining and Antimicrobial Studies: In some biology classes, silver nitrate is used for staining, and its antimicrobial properties can be demonstrated to show how it affects microbial growth.
Because silver nitrate can stain skin and other materials, safety precautions such as gloves and goggles should be used when handling it.
In Skeletal & Muscular Systems, students learn that bones and muscles work together to protect our bodies and enable them to move. They'll discover that, in addition to providing support for our bodies and protecting vital organs, bones are where blood is manufactured! Viewers also learn that bones are classified by shape -- long, short, flat and irregular -- and that there are three types of muscles -- skeletal, smooth and cardiac. Vivid examples and colorful graphics illustrate how joints work with the help of connective tissues like cartilage, ligaments and tendons. An orthopedic surgeon explains how bones heal, and a fun, hands-on experiment shows how calcium is essential for strong, healthy bones.

Discover how scientists are able to learn about the world around us by studying how light interacts with matter. Spectrophotometry gives students an understanding of the principles of spectral analysis and explains the relationship between absorbance and transmittance. Students then go inside the lab to put this information into action as they perform serial dilutions, develop a standard curve and determine the concentration of aspirin in two unknown solutions using a spectrophotometer. In the process, they use proper scientific procedures and come to understand that measurement errors may affect calculations. Part of the multivolume Science Lab Investigations! DVD Series.
