    Yes, a mixture of a tablet of murexide indicator and titrate with EDTA will first turn yellowish green, then deep purple.

    I just love this 1985 movie and could not believe there was not a single quiz about this film. If you have watched it as much as I have these questions should be easy. Otherwise, you may have to see it again!
