Aluminum chloride = AlCl3
CAS# 7446-70-0
MW = 133.340 g/mole
White hexagonal crystals or powder, hydroscopic
MP = 192.6°C
density = 2.48 g/cm³
soluble in benzene, chloroform, CCl4,
solubility in water = 45.1g/100g H2O @ 25°C
fumes in air, strong smell of HCl
Lead Nitrate = Pb(NO3)2
CAS# 10099-74-8
MW = 331.2 g/mole
colorless cubic crystals
MP = 470°C
density = 4.53 g/cm³
soluble in water & ethanol
solubility in water = 59.7g/100g H2O @ 25°C
no smell
Poisonous!
