Chemical formula. K 2 TeO 3 Appearance white crystals, powder Hazards GHS labelling: ... Potassium tellurite, K 2 TeO 3, is an inorganic potassium-tellurium compound. [1]
Potassium telluride is an inorganic compound with a chemical formula K 2 Te. It is formed from potassium and tellurium, making it a telluride. [2] Potassium telluride is a white powder. Like rubidium telluride and caesium telluride, it can be used as an ultraviolet detector in space.
For most ionic compounds dissolved in water, the van 't Hoff factor is equal to the number of discrete ions in a formula unit of the substance. This is true for ideal solutions only, as occasionally ion pairing occurs in solution. At a given instant a small percentage of the ions are paired and count as a single particle.
A tellurite tellurate is a chemical compound or salt that contains tellurite and tellurate anions [TeO 3] 2-[TeO 4] 2-. These are mixed anion compounds , meaning the compounds are cations that contain one or more anions.
It is the ratio of the latter to the former: = i is the van 't Hoff factor, the number of particles the solute splits into or forms when dissolved. b is the molality of the solution. A formula to compute the ebullioscopic constant is: [2]
This improper name persists, especially in elementary textbooks. In biology, the unit "%" is sometimes (incorrectly) used to denote mass concentration, also called mass/volume percentage. A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). This is incorrect because ...
Most tellurite salts contain the TeO 2− 3 ion. Oxidation of its aqueous solution with hydrogen peroxide gives the tellurate ion. It is usually prepared as an aqueous solution where it acts as a weak acid. [1] [3] H 2 TeO 3 + H 2 O ⇌ H 3 O + + HTeO − 3 K a1 = 2 × 10 −3 HTeO − 3 + H 2 O ⇌ H 3 O + + TeO 2− 3 K a2 = 1 × 10 −8
Tellurite is a oxyanion of tellurium with the formula TeO 2− 3.It is the ion of tellurous acid, and is chemically related to tellurium dioxide (TeO 2), whose mineral appearance also bears the name tellurite.
