The SO2 present in air is mainly responsible for acid rain. Its concentration can bé determined by titrating against a standard(known) permanganate solution as follows: 5SO2 + 2MNO41 + 2H20 → _5SO4² + 2Mn*2 + 4H*1 Calculate the number of grams of SO, in a sample of air if 7.37 mL of a 0.00800M KMNO4 solution are required for the titration.

Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.
