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 ...
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.
Sodium hexafluoroarsenate is an inorganic chemical compound with the chemical formula NaAsF 6 ... by the fluorination of sodium arsenate by anhydrous HF—followed by ...
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]
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 · n H 2 O , where n is 2, 7, 8, and 12.
Arsenate readily reacts with metals to form arsenate metal compounds. [2] [3] Arsenate is a moderate oxidizer and an electron acceptor, with an electrode potential of +0.56 V for its reduction to arsenite. [4] Due to arsenic having the same valency and similar atomic radius to phosphorus, arsenate shares similar geometry and reactivity with ...
