The compound can be prepared by treating nickel or nickel(II) carbonate with acetic acid: . NiCO 3 + 2 CH 3 CO 2 H + 3 H 2 O → Ni(CH 3 CO 2) 2 ·4 H 2 O + CO 2. The mint-green tetrahydrate has been shown by X-ray crystallography to adopt an octahedral structure, the central nickel centre being coordinated by four water molecules and two acetate ligands. [5]
4] An alternative scale, the free scale, often denoted pH F, omits this consideration and focuses solely on [H +] F, in principle making it a simpler representation of hydrogen ion concentration. Only [H +] T can be determined, [32] therefore [H +] F must be estimated using the [SO 2− 4] and the stability constant of HSO − 4, K * S: [H +] F ...
Cerium(III) chloride (CeCl 3), also known as cerous chloride or cerium trichloride, is a compound of cerium and chlorine. It is a white hygroscopic salt; it rapidly absorbs water on exposure to moist air to form a hydrate , which appears to be of variable composition, [ 1 ] though the heptahydrate CeCl 3 ·7H 2 O is known.
tert-Butyldimethylsilyl chloride is an organosilicon compound with the formula (Me 3 C)Me 2 SiCl (Me = CH 3). It is commonly abbreviated as TBSCl or TBDMSCl. It is a chlorosilane containing two methyl groups and a tert-butyl group. As such it is more bulky that trimethylsilyl chloride. It is a colorless or white solid that is soluble in many ...
Benzalkonium chloride is a frequently used preservative in eye drops. Typical concentrations range from 0.004% to 0.01%. [17] Stronger concentrations can be caustic [18] and cause irreversible damage to the corneal endothelium. [19] Avoiding the use of benzalkonium chloride solutions while contact lenses are in place is discussed in the literature.
Platinum(IV) chloride is the inorganic compound of platinum and chlorine with the empirical formula PtCl 4. This brown solid features platinum in the 4+ oxidation state. This brown solid features platinum in the 4+ oxidation state.
