- C2 B
- Rate of Reactions
- Depends on...
- Temperature
- Concentration
- Catalyst
- Surface area of solids
- Measuring
- Precipitation
- When a product of the reaction is a precipitate which clouds the solution
- Change in mass
- When a gas is given off, the mass will decrease. You can measure the mass drop
- Precipitation
- Depends on...
- Acids and Metals
- Acid + Metal = Salt + Hydrogen
- Oxides and Stuff
- Metal oxides and Hydroxides are bases
- Acid + Metal Oxide or Hydroxide = Salt + Water
- Ammonia
- Ammonia can be neutralised with HNO3 to make fertiliser
- Metal oxides and Hydroxides are bases
- Making salts
- Metal + Insoluble base
- Using an alkalis
- In a precipitation reaction
- Electrolysis
- Involve oxidation and reduction
- Oxidation is loss
- Reduction is gain
- "Splitting up with electricity"
- Electroplating
- Coating a metal in a thin layer of another metal
- E.g Cheap jewelry
- Coating a metal in a thin layer of another metal
- Involve oxidation and reduction

- Measuring
- Precipitation

- Change in mass
- When a gas is given off, the mass will decrease. You can measure the mass drop
- Precipitation
- Volume of gas given off
- Measuring the amount of gas given off by a reaction in a glass syringe
- Volume of gas given off
- Volume of gas given off
- Rate of reaction = Amount of reactant used or amount of product / Time
- Rate of Reactions

- Acids and Metals
- More collisions increases rate of reaction
- To increase collisions...
- Higher temperature
- Higher concentrations
- C2 B
- Larger surface area
- To increase collisions...
- Higher temperature
- Higher concentrations
- To increase collisions...
- Catalysts
- Collision Theory
- More collisions increases rate of reaction
- Collision Theory
- They speed up reactions by increasing the amount of successful collisions
- Catalysts
- Catalysts
- Therefore they reduce costs in industry
- They speed up reactions by increasing the amount of successful collisions
- They speed up reactions by increasing the amount of successful collisions
- Energy Transfer
- Exothermic
- Heat given out
- Endothermic
- Heat taken in
- Reversible reactions can be exothermic or endothermic
- Exothermic
- Acids and Alkalis
- The pH scale
- Goes from 0-14
- 0 is Acid
- 14 is Alkalis
- Goes from 0-14
- An indicator is a dye that changes colour
- Acids and bases neutralise eachother
- The pH scale
- It shows whether something is acid or alkalis
- An indicator is a dye that changes colour
- HCL will always produce chloride salts
- The combo of metal and acid decides the salt
