Where should spilled NaCl be placed?
Answer: A. Solid waste container.
All excess solid chemicals should go into the solid waste
container, even relatively harmless substances such as sodium
B. Garbage can. Do not put excess chemicals into the garbage can, since
other people cannot tell just by looking at the substance if it
is harmful or not.
C. Organic waste carboy. Solids should never go into the
organic waste carboy.
D. Into your reaction flask, since it's one of the reactants. Never put the excess into your
reaction flask; not only will the chemicals drastically alter
the amount you had previously weighed into the flask, but they
are probably contaminated as well.
E. Back into the NaCl bottle. Never return an excess chemical
to its reagent bottle because you may contaminate the whole bottle.
