1. Rank the following solutions from least polar to most polar. Rank on a scale of 1-4: 1 being the least polar and 4 being the most polar. 50% ISOPROPANOL / H2O 25% ISOPROPANOL / H2O PURE WATER ISOPROPANOL / H2O

50% ISOPROPANOL / H2O - 1

25% ISOPROPANOL / H2O - 2

Pure water - 4

ISOPROPANOL / H2O - 3

Explanation:

More Isopropanol concentration is least polar. When the isopropanol is mixed with water its polarity increases. Pure water is most polar. The polarity of a substance is dependent on its ability to bent and mold in the shape as required.

the product of the pressure and volume is also constant
