Le Chatelier

Used to determine the specific gravity/density of sand, cement and other fine materials, this borosilicate glass specific gravity bottle is developed from ASTM C 188 and ASTM E 694. The body holds approximately 250mL and the capacity of the oval bulb in the neck is 17mL. Volume below the bulb is…

KIMAX®, Le Chatelier type For the determination of the specific gravity of cement, sand and materials of similar fineness For ASTM Standards E 694 and C 188 Marked with “A” to signify adherence to accuracy specifications in U.S. Department of Commerce publication PB-246 623, The…

Students will investigate Le Chatelier’s principle and why it works. They will also investigate this principle by testing several systems at equilibrium and then selecting specific ones to produce the colors of the rainbow based on specific applications of Le Chatelier’s principle. Students will…

Use an overhead projector to study the reaction of Le Chatelier’s principle. Aligned to the Next Generation Science Standards (NGSS)* Disciplinary Core Ideas: PS1.B: ETS1.C Performance Expectations: HS-PS1-6 Cross Cutting Concepts: Stability and Change Engineering Practices: Constructing…

Le Chatelier’s Principle is a qualitative rule, which allows the prediction of the effect of temperature, pressure and concentration changes on chemical reactions. The principle states: A chemical system at equilibrium when stressed by external forces will adjust in such a way as to minimize that…
