Soluble
A solid that dissolves in a liquid solvent.
Insoluble
A solid that does not dissolve easily in a liquid solvent.
Solute
A solid that changes its state during the dissolving process
Solvent
A solid that does not change its state during the dissolving process.
Solution
A mixture containing the solute and the solvent
Residue
Solid particles trapped in filter paper
Filtrate
Liquid particles that pass through the filter paper.
Distillate
The liquid that condenses during distillation and is collected
Miscible
A liquid that mixes easily with another liquid
Immisible
A liquid that doesn’t mix easily with another liquid
Most alkalis are
Soluble, metal hydroxides
Left hand sided elements on the periodic table (metals)
Lose electrons
Right hand sided elements on the periodic table ( non metals)
Gain electrons
Left hand sided elements on the periodic table (metals) form
Positive ions (cations)
Right hand sided elements on the periodic table (non metals) form
Negative ions (anions)
Molecular ion is
Two or more atoms covalently bonded
Ionic bonding occurs when
Opposite charges attract
2 atoms in each molecule is described as
Diatomic
Oxygen atoms share two pairs of electrons. The bond between them is called a
Double bond
Covalent bonds are very
Strong
Metal ions are
Packed tightly together in a regular lattice.
The tight packing of of metallic ions causes
Tight packing causes electrons to get separated from their atoms
What is the result of this tight packing in metal ions
A lattice of positive ions in a delocalised sea of electrons
