Did you know?
WitrynaCorresponding compounds of the hydrogen isotopes differ slightly in their physical properties. This difference is shown by the properties of the waters, listed in the Table, and of the elements, listed in the following Table. The same is true of their chemical properties, both thermodynamic and kinetic. WitrynaHydrogen also has many other uses. In the chemical industry it is used to make ammonia for agricultural fertiliser (the Haber process) and cyclohexane and methanol, which are intermediates in the production of plastics and pharmaceuticals. It is also used to remove sulfur from fuels during the oil-refining process.

Witryna17 wrz 2024 · Detailed Description. pH is a measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Witryna14 wrz 2024 · Hydrogen bonding in water molecules is the reason behind most of its physical and chemical properties. It is the electrostatic force of attraction between highly electronegative oxygen (E.N∼3.4) and partially positive hydrogen (E.N∼2.1).
