Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH.It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −.
For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq). The word aqueous (which comes from aqua) means pertaining to, related to, similar to, or dissolved in, water. [1] [2] As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent ...
X-ray spectrometer developed by W. H. Bragg. In 1913 the structure of sodium chloride was determined by William Henry Bragg and his son William Lawrence Bragg. [2] [3] [4] This revealed that there were six equidistant nearest-neighbours for each atom, demonstrating that the constituents were not arranged in molecules or finite aggregates, but instead as a network with long-range crystalline ...
In molten sodium chloride (NaCl), when a current is passed through the salt the anode oxidizes chloride ions (Cl −) to chlorine gas, it releases electrons to the anode. Likewise, the cathode reduces sodium ions (Na +), which accepts electrons from the cathode and deposits them on the cathode as sodium metal.
Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic , and occurs as the mineral halite .
The apparent molar volume of salt is usually less than the molar volume of the solid salt. For instance, solid NaCl has a volume of 27 cm 3 per mole, but the apparent molar volume at low concentrations is only 16.6 cc/mole. In fact, some aqueous electrolytes have negative apparent molar volumes: NaOH −6.7, LiOH −6.0, and Na 2 CO 3 −6.7 cm ...
At temperatures above 360 K, NaSH adopts the NaCl structure, which implies that the HS − behaves as a spherical anion owing to its rapid rotation, leading to equal occupancy of eight equivalent positions. Below 360 K, a rhombohedral structure forms, and the HS − sweeps out a discoidal shape. Below 114 K, the structure becomes monoclinic.
