2. Separation process - Wikipedia

   en.wikipedia.org/wiki/Separation_process

   A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity.

3. Solvation - Wikipedia

   en.wikipedia.org/wiki/Solvation

   Solvation or dissolution is a kinetic process and is quantified by its rate. Solubility quantifies the dynamic equilibrium state achieved when the rate of dissolution equals the rate of precipitation. The consideration of the units makes the distinction clearer. The typical unit for dissolution rate is mol/s.

4. Tetrasulfur tetranitride - Wikipedia

   en.wikipedia.org/wiki/Tetrasulfur_tetranitride

   Reaction with piperidine generates [S 4 N 5] −: 24 S 4 N 4 + 32 C 5 H 10 NH → 8 [C 5 H 10 NH 2] + [S 4 N 5] − + 8 (C 5 H 10 N) 2 S + 3 S 8 + 8 N 2. A related cation is also known, i.e. [S 4 N 5] +. Triphenylphosphine abstracts a sulfur atom, replacing it with another triphenylphosphine moiety: [14] S 4 N 4 + 2 PPh 3 → S 3 (PPh 3)N 4 ...

5. Dilution (equation) - Wikipedia

   en.wikipedia.org/wiki/Dilution_(equation)

   The equation can only be applied when the purged volume of vapor or gas is replaced with "clean" air or gas. For example, the equation can be used to calculate the time required at a certain ventilation rate to reduce a high carbon monoxide concentration in a room.

6. Colligative properties - Wikipedia

   en.wikipedia.org/wiki/Colligative_properties

   The word colligative is derived from the Latin colligatus meaning bound together. [3] This indicates that all colligative properties have a common feature, namely that they are related only to the number of solute molecules relative to the number of solvent molecules and not to the nature of the solute. [4] Colligative properties include:

7. Equation solving - Wikipedia

   en.wikipedia.org/wiki/Equation_solving

   The solution set of the equation ⁠ x 2 / 4 ⁠ + y 2 = 1 forms an ellipse when interpreted as a set of Cartesian coordinate pairs. Main article: Solution set The solution set of a given set of equations or inequalities is the set of all its solutions, a solution being a tuple of values, one for each unknown , that satisfies all the equations ...

8. Enthalpy change of solution - Wikipedia

   en.wikipedia.org/wiki/Enthalpy_change_of_solution

   The integral heat of dissolution is defined as a process of obtaining a certain amount of solution with a final concentration. The enthalpy change in this process, normalized by the mole number of solute, is evaluated as the molar integral heat of dissolution. Mathematically, the molar integral heat of dissolution is denoted as:

9. Isotope dilution - Wikipedia

   en.wikipedia.org/wiki/Isotope_dilution

   Here, R A is the isotope amount ratio of the natural analyte, R A = n(i A) A /n(j A) A, R B is the isotope amount ratio of the isotopically enriched analyte, R B = n(i A) B /n(j A) B, R AB is the isotope amount ratio of the resulting mixture, x(j A) A is the isotopic abundance of the minor isotope in the natural analyte, and x(j A) B is the ...
