titration:
burette of acid
add regular volume of base
add methyl orange
do rough
repeat but near rough value slow down
swirl
if stays pink = fully nuetralised
if mol ratio = 1:1
conc = mol / volume
-
-
purifying copper :
copper anode , move to cathode
impurities left in solution
-
-
cells / batteries :
metals in solution of own ions will ionis
difference in charrge = electrode potential
-
atoms
atoms cannot be broken down into constituents chemically
compound = 2 or more elements chemically bonded
mixture = 2 or more elements not chemically bonded

Developing periodic table: dalton = weight order
newland = properties
mendeleev columns and groups with gaps
bonding
-
ionic: metal + non metals , metal donates electron , non metal accepts,
ions form latice e.g.crystals
conduct when molten or in solution , as ions are free to move
covalant: non metal + non metal, electrons shared
-
-
Metallic : atoms form lattice, ions surrounded by de localized electrons, so can conduct
