Sodium dihydrogen phosphate Sodium hydrogen phosphate Trisodium phosphate. A sodium phosphate is a generic variety of salts of sodium (Na +) and phosphate (PO 3− 4). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates. Most of these salts are known in both anhydrous (water-free) and hydrated forms ...
Disodium phosphate (DSP), or disodium hydrogen phosphate, or sodium phosphate dibasic, is an inorganic compound with the chemical formula Na 2 H P O 4. It is one of several sodium phosphates . The salt is known in anhydrous form as well as hydrates Na 2 HPO 4 · n H 2 O , where n is 2, 7, 8, and 12.
Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate. The buffer helps to maintain a constant pH.
It is a sodium salt of phosphoric acid. It consists of sodium cations (Na +) and dihydrogen phosphate anions (H 2 PO − 4). One of many sodium phosphates, it is a common industrial chemical. The salt exists in an anhydrous form, as well as monohydrate and dihydrate (NaH 2 PO 4 ·H 2 O and NaH 2 PO 4 ·2H 2 O respectively). [1]
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.
Lysis buffer usually contains one or more salts. The function of salts in lysis buffer is to establish an ionic strength in the buffer solution. Some of the most commonly used salts are NaCl, KCl, and (NH 4) 2 SO 4. They are usually used with a concentration between 50 and 150 mM. [4] Sodium dodecyl sulfate (SDS) structure
The "backbone" of a polyphosphoric acid molecule is a chain of alternating P and O atoms. Each extra orthophosphoric unit that is condensed adds 1 extra H atom, 1 extra P atom, and 3 extra O atoms. The general formula of a polyphosphoric acid is H n+2 P n O 3n+1 or HO[−P(O)(OH)−O−] n H.
At 25 °C (77 °F), solutions of which the pH is less than 7 are acidic, and solutions of which the pH is greater than 7 are basic. Solutions with a pH of 7 at 25 °C are neutral (i.e. have the same concentration of H + ions as OH − ions, i.e. the same as pure water). The neutral value of the pH depends on the temperature and is lower than 7 ...
