Science / Geology / Hydrolysis: A chemical reaction involving water that results in the breakdown of mineral material.

Base Hydrolysis Constant

Science / Chemistry / Base Hydrolysis Constant: The equilibrium constant for the hydrolysis reaction associated with a base. For example, Kb for ammonia is the equilibrium constant for NH3(aq) + H2O(ell) doublearrow NH4+(aq) + OH-(aq), or Kb = [NH4 MORE

Chemical Weathering

Science / Geology / Chemical Weathering: The breaking down of surface rock material by solution or chemical alteration. Common alteration processes are oxidation and hydrolysis. MORE

Calcium (Ca)

Science / Periodic Table of Elements / Calcium (Ca): Atomic number: 20, Atomic mass: 40.08 g.mol -1, Electronegativity: 1.0, Mass volume: 1.6 g.cm-3 at 20°C, Melting point: 840 °C, Boiling point: 1484 °C, Vanderwaals radius: 0.197 nm, Ionic radius: 0 MORE


Science / Chemistry / Pkb: The pkb of an base is minus the base-10 log of its base hydrolysis constant, pkb = - log Kb. For example, a pkb of 5 is equivalent to an base hydrolysis constant of 10-5. MORE


Science / Chemistry / Saponification: The hydrolysis of esters using hot sodium hydroxide solution to produce the salt of a carboxylic acid. Usually saponification refers to the hydrolysis of esters of fatty acids to manufacture soaps. MORE


Science / Chemistry / Monosaccharide: A carbohydrate that cannot be decomposed into simpler carbohydrates by hydrolysis. MORE
