Shelf Life of Chemicals
The safe shelf life of chemicals varies from product to product. Some, like
potassium metal and ether, can become potentially more dangerous. Others
may become less chemically active. If you sometimes wonder why an experiment
did not work, the chemical could be the problem. Review the shelf life
information provided in this Catalog/Reference Manual. Purchase particularly
hazardous chemicals in small quantities so that they are completely
used up in a short time—preferably in less than a year.
