- Acids and Bases
- Ions
- Polyatomic- when there are more than one ion in an atom
- Monoatomic - when there is only one ion in the atom
- Positive ions (cations)
- Negative ions (anions)
- Rates of reaction
- Surface Area
- by increasing this ( cutting up the substance into smaller pieces) the reaction rate will increase because the collisions can occur in more places
- Concentration
- this is the number of reactants in a mixture. decreasing the concentration lowers the rate of reaction and vice versa. concentration in a mixture usually decreses after time
- Catalyst
- these speed up the rate of the reaction without being used up themselves
- Temperature
- increasing the temp increases the kinetic energy. particles with high energy collide with more force. this means that more successful collisions are likely to occur
- Surface Area
- Acids
- Form h+ ions in water
- Sour
- Corrosive
- Ph of less than 7
- When an acid react a metal slat is formed
- Bases
- Form OH- ions in water
- Slippery to touch
- Corrosive to Skin
- Ph more than 7
- Most are insoluble but those that do dissolve are called Alkalis
- Reactions
- Neutralisation
- This is when a metal oxide (acid) combines with a metal hydroxide (base) the products of this are salt and water
- Acid + Carbonate
- this is when a carbonate or hydrogen carbonate reacts to an acid. the products are salt,carbon dioxide and water
- BALANCE YOUR EQUATIONS
- Neutralisation
- Ions
