Let's assume its just papain and not all the extra stuff like the salt and spices. It doesn't say much in the Wikipedia article.

Also I wonder if criminals have used this to get rid of evidence, like dead bodies, or if it can help destroy DNA (blood or semen), like how bleach does with semen. Unless it doesn't break up DNA strands, but just tissue structure.

I'm into science & forensics in general and a big fan of shows like the old Jeremy Brett Sherlock Holmes series, House M.D., but also a huge fan of Horror, especially the reality based stuff like Traces of Death, and the Guinea Pig series.

Thanks!

What observations would you see when you mix a Potassium Sulphate Solution with these respectively:
1. Barium Chloride Solution
2. Dilute Hydrochloric acid
3. Barium chloride solution followed by dilute Hydrochloric acid

Also, what would you observe when you mix these three substances respectively with Potassium Sulphite Solution.

P.S- If you know the answer how did you get to it? From the equations?
Thankyou
