Making Soluble Salts
-
A (acid) + A (alkali)
- HCl(aq) + NaOH (aq) ---> NaCl (aq) + H2O (l)
-
A (acid) + B (base)
- H2SO4 (aq) + CuO (s) ---> CuSO4 (aq) H2O (l)
-
A (acid) + C (carbonate)
- 2HNO3 (aq) + CuCO3 (s) ---> Cu(NO3)2 (aq) + H2O (l)+ CO2 (g)
-
A (acid) + M (metal)
- 2HCl (aq) + Mg (s) ---> MgCl2 (aq) + H2 (g)
-
neutralisation
- Arrhenius' theory
- H+ (aq) + OH- (aq) ---> H2O (l)
-
TITRATION
- acis (aq) + alkali (aq) ---> a salt (aq) + water (l)
-
indicator
- shows end of reaction
- calculate moles of reactants

Arrhenius Acid - Base Theory
- The Arrhenius acid-base concept classifies
a substance as an acid if it produces
hydrogen ions H(+) or hydronium ions in
water. A substance is classified as a base
if it produces hydroxide ions OH(-) in water
-
Bronsted-Lowry Acid-Base Concept
- classifies a substance as an acid if it
acts as a proton donor, and as a base
if it acts as a proton acceptor.
-
Lewis Acid-Base Concept
- The Lewis theory classifies a substance
as an acid if it acts as an electron-pair
acceptor and as a base if it acts as an
electron-pair donor
