(A) double arrows
(B) 1: colour indigo, ph 10
2: colour red, ph 1
(C) Ammnoia has a lower relative molecular mass of 17 than hydrogen chloride with relative molecular mass of 36.5. (2m) Thus ammonia diffuses faster than hydrogen chloride (1m) at the same period of time, this they do not meet in the centre of the tube.
