The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
The two unique forms of potassium arsenite can be attributed to the different number of oxygen atoms. Potassium meta-arsenite (KAsO 2) contains two oxygen atoms one of which is bonded to the arsenic atom via a double bond. Conversely, Potassium ortho-arsenite (K 3 AsO 3) consists of three oxygen atoms all bound to the arsenic atom via single bonds.
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
Potassium arsenate usually refers to tripotassium arsenate K 3 AsO 4 but may also refer to: Monopotassium arsenate, KH 2 AsO 4; Dipotassium arsenate, K 2 HAsO 4; See ...
In chemistry, an arsenite is a chemical compound containing an arsenic oxyanion where arsenic has oxidation state +3. Note that in fields that commonly deal with groundwater chemistry, arsenite is used generically to identify soluble As III anions.

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 ...
