Job first published his method in 1928, while studying the associations of ions in solution. [1] By plotting the UV absorbance of a solution of Tl(NO 3 )/NH 3 against the mole fraction of Tl(NO 3 ) , he produced a graph which provided information about the equilibrium complexes present in solution.
Gas stoichiometry is the quantitative relationship (ratio) between reactants and products in a chemical reaction with reactions that produce gases. Gas stoichiometry applies when the gases produced are assumed to be ideal, and the temperature, pressure, and volume of the gases are all known. The ideal gas law is used for these calculations.
The propensity for any two substances to form a solid solution is a complicated matter involving the chemical, crystallographic, and quantum properties of the substances in question. Substitutional solid solutions, in accordance with the Hume-Rothery rules, may form if the solute and solvent have: Similar atomic radii (15% or less difference)
Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. [1] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2]
Stoichiometry is used to run calculations about chemical reactions, for example, the stoichiometric mole ratio between reactants and products. The stoichiometry of a chemical reaction is based on chemical formulas and equations that provide the quantitative relation between the number of moles of various products and reactants, including yields ...

A spectator ion is an ion that exists both as a reactant and a product in a chemical equation of an aqueous solution. [1] For example, in the reaction of aqueous solutions of sodium carbonate and copper(II) sulfate: 2 Na + + CO 2− 3 (aq) + Cu 2+ (aq) + SO 2− 4 (aq) → 2 Na + (aq) + SO 2− 4 (aq) + CuCO 3
