inorganic chemistry Flashcards
1
Q
MgO + H2O
A
Mg(OH)2
2
Q
P4O10 + H2O
A
H3PO4
3
Q
SO3 + H2O
A
H2SO4
4
Q
Na2O + H2O
A
NaOH
5
Q
MgCl + H2O
A
(i) [Mg(H2O)6]2+
- high charge density
- covalent character
(ii) [Mg(H2O)6]2+ + H2O –> [Mg(OH)(H2O)]+ + H3O+
- dissolves in water
- hydrated magnesium ion undergoes slight hydrolysis to give acidic solution pH6.5
6
Q
PCl + H2O
A
(i) (4H2O) H3PO4 + HCl
- undergoes complete hydrolysis
- very acidic solution pH1-2
(ii) (1H2O) POCl3 + HCl
- limited supply of water
produces trichloride oxide
- PCl5 fumes in moist air
7
Q
AlCl3 + H2O
A
Al(OH)3
- limited H2O, white solid, white fumes evolved
8
Q
SiCl4 + H2O
A
SiO2 * 2H2O
- complete hydrolysis, very acidic solution
