When a substance sublimates it passes from a solid to a gas without first melting into a liquid.  In addition to iodine, both naphthalene (which makes moth balls) and carbon dioxide  (which makes dry ice) sublimate.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

the ratio of the conjugate base to the acid required to attain the desired ph.
