41Potentiometer (measuring instrument) — A potentiometer is an instrument for measuring the potential (voltage) in a circuit. Before the introduction of the moving coil and digital volt meters, potentiometers were used in measuring voltage, hence the meter part of their name. The method …
42Sodium hydroxide — Sodium hydroxide …
43Conductivity (electrolytic) — The conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and… …
44Ammonium cyanide — Ammonium cyanide …
45Methadone — Phy redirects here. For the abbreviation for the physical layer of the OSI Model, see PHY. Not to be confused with Methedrine, Methedrone, Mephedrone, or Methylone. Methadone …
46Differential pulse voltammetry — (AKA Differential Pulse Polarography or DPP) is often used to make electrochemical measurements. It can be considered as a derivative of linear sweep voltammetry or staircase voltammetry, with a series of regular voltage pulses superimposed on… …
47Point of zero charge — The point of zero charge (pzc), in physical chemistry, is a concept relating to the phenomenon of adsorption, and it describes the condition when the electrical charge density on a surface is zero. It is usually determined in relation to an… …
48Ph — Chem. phenyl. * * * Quantitative measure of the strength of the acidity or alkalinity (see acid, base) of a solution. It is defined as the negative common logarithm of the concentration of hydrogen ions [H+] in moles/litre: pH = log10 [H+]. The… …
49pH — Chem. the symbol for the logarithm of the reciprocal of hydrogen ion concentration in gram atoms per liter, used to express the acidity or alkalinity of a solution on a scale of 0 to 14, where less than 7 represents acidity, 7 neutrality, and… …
50ph — Optics. phot; phots. * * * Quantitative measure of the strength of the acidity or alkalinity (see acid, base) of a solution. It is defined as the negative common logarithm of the concentration of hydrogen ions [H+] in moles/litre: pH = log10 [H+] …
