Below is an essay on "Solubility of Certain Alcohols" from Anti Essays, your source for research papers, essays, and term paper examples.

The aim of this practical was to investigate and inspect the solubility of unlike alcohols in distilled water.

We concluded in our Hypothesis that alcohols have three options depending on the alcohols solubility. They either dissolved, partially dissolved or did not dissolve at all.
Five 20ml glass beakers
Methanol, pentanol, ethanol, propanol, butanol, glycerine.
Distilled water
2x 5 mL measuring cylinders
Step 1) Pour 5 mL of distilled water into the 5mL measuring cylinder. Then select one of the five alcohols and add 5 drops of each alcohol with the 5 milliliters of water.
Step 2) Let the solution sit for one minute to make sure that the result will be clear
Step 3) After you carefully observe the beaker with the solution, make sure you wash it thoroughly before using It for the next trial/test.
Repeat for all six types of alcohols using the same apparatus every time to make sure the result are as accurate as possible.

| Methanol | Pentanol | Ethanol | Propanol | Glycerine | Butanol |
Soluble | | | YES | | YES | |
Insoluble | | YES | | | | |
Partially Soluble | YES | | | YES | | YES |

The data together unevenly displays that the alcohols with larger molecules have less solubility in distilled water. Ethanol and glycerine were soluble, whereas methanol, propanol and butanol were partially soluble. Pentanol indicated no signs of solubility at all. This can be seen on the results table above the discussion.
The data corresponds with the molecular structure of each alcohol type. As each molecule gains more carbon chains, the solubility of that alcohol seems to decrease. Glycerine is the only alcohol that does not abide by the law completely, as it has three hydroxyl groups. Having three hydroxyl groups seemed to help Glycerine’s solubility. Statistics show, the lower the ratio of hydroxyl groups to carbon chains, the less solubility the alcohol has.
The independent variable...
