ION PRODUCT OF HASIL DARAB ION (KW) The product of H ion and OH ion concentration at a
WATER (KW) particular temperature.
+
pH pH A convenient way to express the concentration of H3O
in solution :
+
pH = -log10[H3O ]
-
pOH pOH A convenient way to express the concentration of OH
in solution :
-
pOH = -log10[OH ]
SALT HYDROLYSIS HIDROLISIS GARAM A chemical reaction between anion and / or cation of a
salt, with water molecules.
SOLUBILITY KETERLARUTAN The amount of that substance that will dissolve in a
given amount of solvent.
SOLUBILITY PRODUCT, HASIL DARAB An equilibrium constant for the equilibrium between an
(Ksp) KETERLARUTAN, (Ksp) insoluble or slightly soluble electrolyte and a saturated
aqueous solution containing the ions of the electrolyte.
+
STRONG ACID ASID KUAT An acid that is fully ionised to form H3O ions in aqueous
solution.
-
STRONG BASE BES KUAT A base that is fully ionised to form OH ions in aqueous
solution.
TITRATION CURVE LENGKUNG PENTITRATAN A plot of the pH of the solution versus the volume of
added titrant. Because there is a sharp change in pH at
the equivalent point, the volume of titrant required to
reach the equivalent point can be determined precisely.
+
WEAK ACID ASID LEMAH An acid that is partially ionised to form H3O ions in
aqueous solution.
-
WEAK BASE BES LEMAH A base that is partially ionised to form OH ions in
aqueous solution.

If you are not part of the solution,

then you are part of the precipitate!
