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.
2 KOH + CO 2 → K 2 CO 3 + H 2 O. From the solution crystallizes the sesquihydrate K 2 CO 3 ·1.5H 2 O ("potash hydrate"). Heating this solid above 200 °C (392 °F) gives the anhydrous salt. In an alternative method, potassium chloride is treated with carbon dioxide in the presence of an organic amine to give potassium bicarbonate, which is ...
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.
potassium hydroxide (KOH) Carbonate of potash, salts of tartar, or pearl ash: potassium carbonate (K 2 CO 3) Chlorate of potash: potassium chlorate (KClO 3) Muriate of potash (MOP) potassium chloride (KCl:NaCl = 95:5 or higher) [1] Nitrate of potash or saltpeter: potassium nitrate (KNO 3) Sulfate of potash (SOP) potassium sulfate (K 2 SO 4 ...
About 112 g of KOH dissolve in 100 mL water at room temperature, which contrasts with 100 g/100 mL for NaOH. [14] Thus on a molar basis, KOH is slightly more soluble than NaOH. Lower molecular-weight alcohols such as methanol, ethanol, and propanols are also excellent solvents. They participate in an acid-base equilibrium.
Hydrochloric acid – HCl(aq) Hydrogen chloride – HCl; Hypochlorous acid – HOCl; Indium(I) chloride – InCl; Indium(III) chloride – InCl 3; Iodine monochloride – ICl; Iridium(III) chloride – IrCl 3; Iron(II) chloride – FeCl 2; Iron(III) chloride – FeCl 3; Lanthanum chloride – LaCl 3; Lead(II) chloride – PbCl 2; Lithium ...
Powdered potassium sulfide anhydrous. Potassium sulfide is an inorganic compound with the formula K 2 S.The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH).
The "size" of the charge in an ionic bond depends on the number of electrons transferred. An aluminum atom, for example, with a +3 charge has a relatively large positive charge. That positive charge then exerts an attractive force on the electron cloud of the other ion, which has accepted the electrons from the aluminum (or other) positive ion.
