Module 2.1
- Ionic Equations
- Show only the ions involved
in the reaction
- Only ionic substances dissolved in a
solvent (aq) split into ions
- Solid ionic substances will not
separate into individual ions
- Acids are classed as ionic because they split
into their components in a solution
- Show only the ions involved
in the reaction
- Molecular Ions
- Nitrate= NO3, 1- charge
- Hydroxide= OH, 1- charge
- Carbonate= CO3, 2- charge
- Sulphate= SO4, 2- charge
- Ammonium= NH4, 1+ charge
- Nitrate= NO3, 1- charge
- Ideal Gas Equation: p= Pressure (Pa), V= Volume (m3), n= Moles,
R= Gas constant (8.31JK1-mol1-), T= Temperature (K)
- Metals in Group 1 will always have a +1 charge
- Non-metals are negatively charged ions
- Avagadro's Number: (6.02 x 10^23). This is a constant.
- Types of Reactions
- Acid + Base ---> Salt + Water
- Acid + Alkali ---> Salt + Water
- Acid + Carbonate ---> Salt + Water + Carbon Dioxide
- Redox= Reduction and Oxidation
- Acid + Base ---> Salt + Water
