@The diagram shows the apparatus used to find the volume of acid required to react totally with a certain amount of alkali. The name for this process is:
#bur1
Titration
Oxidation
Electrolysis

@The diagram shows the apparatus used in a titration experiment. Acid flows through a thin tube X into a conical flask, which contains alkali. The correct name for tube X is a:
#bur1
Burette
Pipette
Syringe

@Acid (in burette X) is slowly added to an alkali (in flask Y) until it is just neutralised. At this point you have reached:
#bur1
"The end point"
"A neutral reaction"
"Equilibrium"

@Acid (in burette X) is slowly added to an alkali. An indicator is also in the alkali. The indicator is there:
#bur1
To show when all the alkali neutralised
To act as a catalyst
To absorb any excess heat energy produced by the reaction
