The Pourbaix diagram for chromium in pure water, perchloric acid, or sodium hydroxide [1] [2] Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals. The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium ...
Chrome alum or Chromium(III) potassium sulfate is the potassium double sulfate of chromium. Its chemical formula is KCr(SO 4) 2 and it is commonly found in its dodecahydrate form as KCr(SO 4) 2 ·12(H 2 O). It is used in leather tanning. [1]
Chromium acetate hydroxide is the coordination complex with the formula [Cr 2 (OH) 3 (OAc) 3] 4. A dark violet solid, it crystallizes as the triacontatetrahydrate (34 molecules of water of crystallization). It is water soluble. [1]
Chromium(III) acetate, commonly known as basic chromium acetate, [2] describes a family of salts where the cation has the formula [Cr 3 O(O 2 CCH 3) 6 (OH 2) 3] +. The trichromium cation is encountered with a variety of anions, such as chloride and nitrate. Data in the table above are for the chloride hexahydrate, [Cr 3 O(O 2 CCH 3) 6 (OH 2) 3 ...
It can be prepared by treating a potassium-containing base such as potassium hydroxide or potassium carbonate with acetic acid: CH 3 COOH + KOH → CH 3 COOK + H 2 O. This sort of reaction is known as an acid-base neutralization reaction. At saturation, the sesquihydrate in water solution (CH 3 COOK·1½H 2 O) begins to form semihydrate at 41.3 ...
The use of dichromate cleaning solutions is now phased out due to the high toxicity and environmental concerns. Modern cleaning solutions are highly effective and chromium free. [93] Potassium dichromate is a chemical reagent, used as a titrating agent. [94] Chromates are added to drilling muds to prevent corrosion of steel under wet conditions ...
C. Chrome alum; Chromite (compound) Chromium acetate hydroxide; Chromium nitride; Chromium(III) 2-ethylhexanoate; Chromium(III) acetate; Chromium(III) acetylacetonate
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.
