In fish and chip shops, potatoes are cut into chips
several hours before the chips are
cooked. The amount of water in the chips must be
kept constant during this time.
To keep the water in the chips constant, the chips
are kept in salt solution.
A student investigated the effect of different
concentrations of salt solution on the mass of five
chips.
He weighed each one of the five chips.
He placed each chip into a different
concentration of salt solution.
After one hour he removed the chips from the
salt solutions and then reweighed the chips.
(a) (i) In which concentration of salt solution did
the chip gain mass?
(ii) Explain why the chip gained mass in this
solution.
b) In which concentration of salt solution should
the chips be kept in the shop?
Give the reason for your answer.
