A

It’s a clear colourless liquid
Freezes at 0°c and boils at 100ºc
Water density of 1g/cm3
Water is neutral (ph7)
Water has the chemical formula H2O and is a covalent molecule
Most ionic compounds are soluble in water

Q

The solubility of a substance can be determened using the following equation

A

Solubility (g)/ 100g of water = mass of solute x 100
Mass of solvent

Q

The solubility of gases at a higher temperature is problematic as

A

Oxygen becomes less soluble meaning less oxygen available for animal life . In addition c02 is less soluble resulting in an increase in gaseous c02 in the atmosphere further contributing to global warming.

Q

What are the units for each axis for solubility curves

A

X axis = temperature /°c
Y axis = solubility /g/100g

Q

Covalent molecule

A

A molecule that has atoms covalnetly bonded
Which means 2 atoms that share 1 or more pairs of electrons e.g h2O , NaCl

Q

Ionic compound

A

A chemical compound that has positive and negative ions held together by strong electrostatic forces called ionic bonds
