- Half-cell potential
- Half-cell potential is the potential of an electrochemical half-cell with respect to the standard hydrogen electrode.
- Halogens
- Halogens is the reactive nonmetals that are in Group 17 of the periodic table (F, Cl, Br, I, and At). Compounds of these elements are called halogenides or halides.
- Hardness
- Hardness is the resistance of a material to deformation, indentation, or scratching. Hardness is measured on various scales, such as Mohs, Brinell, Knoop, Rockwell, and Vickers.
- Heat of atomization
- Heat of atomization is energy needed to decompose one mole of a certain substance into atoms.
- Heat of fusion
- Heat of fusion is energy absorbed during the change of a mole of a solid to liquid without a change in temperature.
- Heat of vaporization
- Heat of vaporization is energy absorbed during the change of a mole of liquid to a vapor without a change in temperature.
- HPLC
- High-Performance Liquid Chromatography (HPLC) is a term for columm methods in which the mobile phase is a liquid, often under pressure.
