hi all,

I have just had a teacher make some hydrogen sulphide by bubbling a combination of HCL and sodium sulphide through copper sulphate. Now I know that this my be a silly question but how do I now dispose of it???

Is it ok to just throw it all away including the left over reactants??

I have looked through all of the books and have NO idea...

thanks
