But,  For every action there is an equal and opposite reaction.  Therefore if you use muscles to move your hand down faster than falling under gravity, would you not tend to move upward in opposition to the downward motion of your hand ?  I know you can catch falling items on Earth but will it work under 1/6 G ?
Yes, it'll be easier to do in 1/6th.

You can rely on the weight (and inertia, actually) of your whole body to offset the acceleration of your hand faster than gravity.

Well, maybe there isn't that much perchlorate after all. Turns out some of MRO's data wasn't processed correctly:

Can't find the article atm but a much simpler and more relevant "ISRU" method was suggested to perchlorate reduction in the local regolith IIRC; mix it with the "waste' stream. From what I recall it is 'mutually reducing' in both directions.

the perchlorate would be reduced by the "waste" ultimately to chloride. The waste would be oxidized by the perchorate untimately to carbon dioxide.

This is not remotely likely to happen because
1) Waste is unlikely to be released into the Marian ebvironment for planetary protection reasons - we don't realy want to be contaminating the Martian environment do we?
2) Space suits will need to be resistant to perchorate but it should be reasonably easy to prevent its entry into the spacecraft in any meaningful amounts by careful design of how the suits are entered and/or by electrostic / chemical decontamination.
