The solid compound na4sio44 contains
How to Calculate the Solubility Product Constant
When an ionic compound, such as silver chloride (AgCl), is added to water, an equilibrium is established between the solid compound and its constituent ions in solution: AgCl (s) ⇌ Ag + (aq) + Cl – (aq) The solubility
Melting Point and Thermometer Calibration
A compound is also pure when the mixed melting point of equal portions of the compund and an authentic melting point sample is sharp and not depressed. The identity of a solid can be determined when pure authentic
Weighing compounds using a balance
Weighing is done to ensure the correct amount of a reactant is added to a reaction, for the preparation of standard solutions or the weighing of a product to calculate a yield. Video: Weighing compounds using a balance video
Examples, Alloys and Definition
Solid-solid solutions such as brass, bronze, and sterling silver are called alloys. Bronze (composed mainly of copper with added tin) was widely used in making weapons in times past dating back to at least 2400 B.C. This
The Composition and Application of Filter Paper
In experiments, uses of filter paper together with the filter funnel and Brinell funnel. Because filter paper composition is fibers, there are numerous holes on its surface for liquid particles to pass through, while larger solid
