Green slime is NOT acidic.
Green Slime (CR 4): This dungeon peril is a dangerous variety of normal slime. Green slime devours flesh and organic materials on contact and is even capable of dissolving metal. Bright green, wet, and sticky, it clings to walls, floors, and ceilings in patches, reproducing as it consumes organic matter. It drops from walls and ceilings when it detects movement (and possible food) below.
A single 5-foot square of green slime deals 1d6 points of Constitution damage per round while it devours flesh. On the first round of contact, the slime can be scraped off a creature (destroying the scraping device), but after that it must be frozen, burned, or cut away (dealing damage to the victim as well). Anything that deals cold or fire damage, sunlight, or a remove disease spell destroys a patch of green slime. Against wood or metal, green slime deals 2d6 points of damage per round, ignoring metal's hardness but not that of wood. It does not harm stone.
I bolded a few items, as you can see green slime damage is untyped. It is just in your face damage.
Anything organic is disolved by it on contact. Metal and wood are also disolved by doing damage to them. Only thing unharmed is stone. If it was acidic it would damage stone as well.
Green Slime is down right nasty. Whatever is used to scrap the green slime off is destroyed no save, nothing "destroying the scraping device". Your Holy Avenger gets destroyed if you use it to scrape off green slime, unless it is happened to be made of stone. Artifacts are immune by their own nature.

The reproduction of green slime does not have a lot of details, but it hints at something very nasty.
..reproducing as it consumes organic matter...
One 5 foot patch of green slime lands on poor PC. PC take 1d6 con damage as the slime begins to disolve him. It has not consumed some organic matter (the PC, and possibly some of his gear). If the PC is unable to scrape off the green slime or destroy it does the green slime reproduce?
By the wording I would say so. Therefore on the second round the PC now has two 5 foot patches on him, as the flesh and gear that was disolved causes the green slime to reproduce creating more green slime. The PC would take 2d6 con damage on the second round.
Would the flesh and gear being disolved cause on the third round for the poor PC to now have 4 patches on him, taking 4d6 con damage?!?!?!?!?

Green slime converts flesh (or whatever it eats) into more green slime. This isn't acid damage. It's Constitution damage, basically—it represents a physical loss of structure akin to lopping off a hand or a foot or whatever part of the body the slime eats. Acid resistance/immunity doesn't help.
Thanks, any guidelines on how much it need to consume to reproduce?

Much like the rest of us.
Tell me about it. :D
Would it be reasonable say completely devouring one medium sized object allows the slime to grow by 5 feet.
I am having a 20 foot pit filled 10 feet deep with green slime used to dispose of people and leaving no trace behind.
Presumably every time they feed a few people to the slime a burst of freeze ray or burning hands would suffice to shrink the slime back so it didn't spill over.
