Chemistry revision Topic 5: Titration, Dynamic equilibria and Fuel cells
Titration:
An experiment used to see what volume of a reactant is needed to react completely with a certain volume of another reactant
Indicator:
-
-
Methyl orange, phenolphthalein and litmus all give sharp colour changes at a specific pH
Haber process:
-
-
Conditions:
Cost of extracting and refining raw materials affects if the process is economically viable(workable) or not
Energy costs affects how profitable a reaction is (high temperature and pressures cost more to maintain)
Important to be able to control the conditions to maximise yield but to keep reaction running at an acceptable rate
-
-
-
-
Pressure:
Higher pressures favour forward reaction so higher pressures increases yield of ammonia and rate of reaction
-
-
Fuel cells:
-
A chemical cell supplied with a fuel and oxygen and uses the reaction between them, to efficiently release energy
-
-
Fertilisers:
Plants need nitrogen, phosphorus and potassium from the soil, fertiliser used to replace or provide more of these nutrients
-
-
-
Ammonia can react with oxygen and water->nitric acid, this can react with ammonia to produce ammonium nitrate(found in fertilisers)
