Organic Acids consisting of carbon, hydrogen and oxygen
1 of 15
Where do mineral acids come from?
Inorganic or Mineral sources
2 of 15
Define 'titration'
a technique used to determine an unknown concentration of an unknown solution using a known concentration of another solution
3 of 15
What type of reaction gives off energy to the environment?
An 'exothermic' reaction
4 of 15
What type of reaction takes in energy from the environment
An 'endothermic' reaction
5 of 15
Define the energy changes that must be controlled by the chemical industry
Fuel required for endothermic reactions costs money. Energy given out by a reaction can be used elsewhere in the plant
6 of 15
give examples of reactions that give out energy
combustion and neutralisation
7 of 15
If the temperature of the products has increased what reaction has taken place?
Exothermic
8 of 15
According to ionic theory, what must a compund do to be considered an acid when dissolved in water?
Any compound is considered an acid if it produces hydrogen ions when dissolved in water
9 of 15
What makes a compound an alkali?
when the compound dissolves, hydroxide ions are added to the solution it is dissolved in
10 of 15
Name some non-metal ions
Carbonate, Hydroxide, Nitrate, Sulfate
11 of 15
define 'rate of reaction'
the quantity of a product produced in a fixed time or the quantity of reactant used up in a fixed time.
12 of 15
Name factors that affect rate of reaction
Concentration, Surface area of the solids, Temperature, Catalysts
13 of 15
Define a 'catalyst'
a substance that alters the rate of reaction. Catalysts do not get used up in experiments, they always remain at the end of the reaction.
14 of 15
Name ways in which you can control the rate of reaction
Measure evolution of gas in a given time. Record loss of mass in a given time. Record loss of solid in a given time. Time how long it takes for an insoluble solid to be produced.
