Disodium hydrogen arsenate is the inorganic compound with the formula Na 2 HAsO 4. 7H 2 O. The compound consists of a salt and seven molecules of water of crystallization although for simplicity the formula usually omits the water component. The other sodium arsenates are NaH 2 AsO 4 and Na 3 AsO 4, the latter being called sodium arsenate ...
Sodium arsenate is the inorganic compound with the formula Na 3 AsO 4. Related salts are also called sodium arsenate, including Na 2 HAsO 4 (disodium hydrogen arsenate) and NaH 2 AsO 4 (sodium dihydrogen arsenate). The trisodium salt is a white or colourless solid that is highly toxic. It is usually handled as the dodecahydrate Na 3 AsO 4. 12H ...
Sodium dihydrogen arsenate is the inorganic compound with the formula NaH 2 AsO 4. Related salts are also called sodium arsenate, including Na 2 HAsO 4 (disodium hydrogen arsenate) and NaH 2 AsO 4 (sodium dihydrogen arsenate). Sodium dihydrogen arsenate is a colorless solid that is highly toxic. The salt is the conjugate base of arsenic acid: H ...
Sodium hexafluoroarsenate is an inorganic chemical compound with the chemical formula NaAsF 6 ... by the fluorination of sodium arsenate by anhydrous HF—followed by ...
A colorful example is cobalt(II) chloride, which turns from blue to red upon hydration, and can therefore be used as a water indicator.. The notation "hydrated compound⋅n H 2 O", where n is the number of water molecules per formula unit of the salt, is commonly used to show that a salt is hydrated.
These reactions take place even at room temperature, and result in a discolouration of the original chemical. [3] Sodium dihydrogen arsinide NaAsH 2 reacts with alkyl halides RX (where X = F, Cl, Br, I, and R is alkyl) to make dialkylarsine AsHR 2. Potassium dihydrogen arsinide KAsH 2 reacts with alkyl halides to make trialkylarsine AsR 3. [4]
This reaction generates glucose-6-arsenate and 6-arsenogluconate, which act as analogs for glucose-6-phosphate and 6-phosphogluconate. [40] At the substrate level, during glycolysis , glucose-6-arsenate binds as a substrate to glucose-6-phosphate dehydrogenase, and also inhibits hexokinase through negative feedback. [ 40 ]
Disodium phosphate (DSP), or disodium hydrogen phosphate, or sodium phosphate dibasic, is an inorganic compound with the chemical formula Na 2 H P O 4. It is one of several sodium phosphates. The salt is known in anhydrous form as well as hydrates Na 2 HPO 4 ·nH 2 O, where n is 2, 7, 8, and 12. All are water-soluble white powders. The ...
