Measuring rates of reaction
Diagram:
Equipment:
Conical flask, delivery
tube, bung, trough,
measuring cylinder.
Conical flask, light
sensor, lamp.
What it measures:
Time taken for X to
disappear when a
precipitate forms e.g.
sodium thiosulphate
and hydrochloric acid.
Volume of gas released
e.g. carbon dioxide
when marble chips
react with acid.
Conical flask, delivery
tube, clamp stand, gas
syringe, bung.
Decrease in mass due
to loss of gas e.g.
carbon dioxide when
marble chips react with
acid.
Conical flask, piece of
paper with an X on it.
Light passing through a
solution when a solid
precipitate forms e.g.
sodium thiosulphate
and hydrochloric acid.
Conical flask, cotton
wool, balance.
