Acid Pools - Sulphuric Acid

With the release of the Chaos Cubed update, it seems like the perfect time to add a new liquid, Sulphuric Acid, we only have two liquids in the game and it would be really great to have a liquid that has item buoyancy but damages mobs. We could use this new liquid to do many things within Minecraft. You could even have selective dissolution with it where it destroys organics only, leaving things like iron ingots etc intact which might be helpful for certain farms. Could then be highly damaging if unarmoured or not very effective if using full armour. Even you could have a potion of corrosion that deals slow damage over time for a long period and whilst affected you take double armour durability damage
