It describes the motion of the ppt. or hydrogen after the reaction
For example,
HCl + Na = NaCl + H2 with the upward arrow in place after H2 to describe that hydrogen will move upwards
For example,
HCl + Na = NaCl + H2 with the upward arrow in place after H2 to describe that hydrogen will move upwards

I wanted it clear and brief
its simple upward arrow is simply to indicate that a gas have evolved
and the downwards arrow describe that a precipitate has formed
Ok thanks
for example, NaSO4 + BaCl - - > BaSO4 +NaCl
BaSO4 is the precipitate so a downward arrow would be shown
