- Percentage Yield
- May not get 100% yield because
- Reaction may be reversible
- Some of reactant or product may be left behind in apparatus such as when filtering or pouring
- Some reactants may react in ways different to the expected reaction (side reactions which produce by products)
- Amount of product obtained is yield
- % yield = actual mass of product / theoretical mass of product x 100
- Worked Example
- Yields in salt preparation
- A double salt contains more than one cation or anion
- They form when a solution of 2 simploe salts crystallises to form a single substance
- Example
- May not get 100% yield because
