While we can sweat to stay cool, dogs pant to release heat. Preventive Vet says that as the moisture on dog tongues and noses evaporates, air circulates through their lungs so their bodies slowly ...
Like other hypophosphites, sodium hypophosphite can reduce metal ions back into base metal. This forms the basis for electroless nickel plating (Ni-P), which is its main industrial application. [2] With this method, a durable nickel-phosphorus film can coat objects with irregular surfaces, such as in avionics, aviation and the petroleum field.
They are anions HP(O) 2 OH −. A typical derivative is the salt [NH 4][HP(O) 2 OH]. [7] [6] Many related salts are known, e.g., RbHPHO 3, CsHPHO 3, TlHPHO 3. These salts are prepared by treating phosphorous acid with the metal carbonate. These compounds contain a layer polymeric anion consisting of HPO 3 tetrahedra linked by hydrogen bonds ...
A phosphate phosphite is a chemical compound or salt that contains phosphate and phosphite anions (PO 3 3-and PO 4 3-). These are mixed anion compounds or mixed valence compounds. Some have third anions. Phosphate phosphites frequently occur as metal organic framework (MOF) compounds which are of research interest for gas storage, detection or ...
Mixed-anion compounds, heteroanionic materials or mixed-anion materials are chemical compounds containing cations and more than one kind of anion. The compounds contain a single phase, rather than just a mixture.
This means that salts of the mono- and di-phosphate ions can be selectively crystallised from aqueous solution by setting the pH value to either 4.7 or 9.8. In effect, H 3 PO 4, H 2 (PO 4) − and H(PO 4) 2− behave as separate weak acids because the successive pK a differ by more than 4. Phosphate can form many polymeric ions such as ...
When crystallized from water, it forms a hexahydrate, but it dehydrates above room temperature. Pyrophosphate is a polyvalent anion with a high affinity for polyvalent cations, e.g. Ca 2+. Disodium pyrophosphate is produced by heating sodium dihydrogen phosphate: 2 NaH 2 PO 4 → Na 2 H 2 P 2 O 7 + H 2 O
Metal aqua ions are always accompanied in solution by solvated anions, but much less is known about anion solvation than about cation solvation. [ 6 ] Understanding of the nature of aqua ions is helped by having information on the nature of solvated cations in mixed solvents [ 7 ] and non-aqueous solvents , such as liquid ammonia , methanol ...
