not actually killing the fish!

:)
Well, my school is located near a small lake, in the experiment to make C2H2 from CaC2, I had some CaC2 left, so I put them into the lake, the next day, when I came to school, I saw the dead fish ;D, that's the truth, and now, I want to know the reason ???

I know the reaction:
CaC2 + 2H2O--> Ca(OH)2 + C2H2
But I don't understand that whether Ca(OH)2 or C2H2 is the cause of the death ???

Ca(OH)2 is a base, C2H2 is an alkyl.
Do you mean that Ca(OH)2 cause alkali environment so that the creatures die

C2H2 is an unsaturated hydrocarbon

Check MSDS (search on the left, or just Google "acetylene MSDS") or at least wikipedia for acetylene toxicology.
