Primary standards are typically used in titration to determine an unknown concentration and in other analytical chemistry techniques. Titrationis a process in which small amounts of a reagent are added to a solution until a chemical reaction occurs. The reaction confirms that the solution is at a specific … See more It might seem odd that a reagent is needed to establish the concentration of a chemical in solution. In theory, it should be possible to simply divide the mass of the chemical by the volume of the solution. But in practice, this … See more A related term is secondary standard, a chemical that has been standardized against a primary standard for use in a specific analysis. Secondary standards are commonly used to calibrate analytical methods. NaOH, once … See more WebNov 1, 2024 · The formula mass of this compound (NaCl) would be 58.43 g/mol. Putting this all together, we discover the following: 1.0 M = 1.0 mol of NaCl / L. .400 L of standard solution = 1.0 mol / 1 L = .400 ...

WebOct 14, 2024 · 9. Mixing Ferrofluids to Make Magnetic Ink. Ferrofluids, fluids whose shape can be changed by magnetic fields, are made by combining ferromagnetic materials (like iron or nickel) with a surfactant and a carrier fluid. When combined, the ferromagnetic particles are suspended in the solution rather than dissolved. WebThis solution can then be titrated with an acidic primary standard solution, such as potassium hydrogen phthalate, KH(C 8 H 4 O 4), in order to determine the concentration of the basic solution more accurately. Because the accurate concentration of the base has been derived using a primary standard, the base is referred to as a secondary standard. WebNov 7, 2024 · A secondary standard has a less purity than a primary standard. These are less stable and chemically reactive than primary standards.
