Why aren't descriptive investigations repeatable?

In descriptive investigations, we still haven't formed any hypothesis yet so we seek information by asking question.

It's not repeatable because repeating the questions over and over again without any clue about what we want to seek is completely waste of time.

Hope this helps xox :)

Answer:

Descriptive investigations are not repeatable because they are based only on observations made at a single point in time. The results may vary at a different time. In addition, descriptive investigations do not contain variables that may indicate cause-and-effect relationships.

<h2>CH_3CH_2OH  →  CH_3CHO </h2>

Explanation:

Ethanol can be oxidized to ethanal or acetaldehyde which is further oxidized to acid that is acetic acid.

CH_3CH_2OH→  CH_3CHO [oxidation by loss of hydrogen]

  • An oxidizing agent potassium dichromate(VI) solution is used to remove the hydrogen from the ethanol.  
  • An oxidizing agent used along with dilute sulphuric acid for acidification.

Acetaldehyde can also be reduced back to ethanol again by adding hydrogen to it by using a reducing agent that is sodium tetrahydro borate, NaBH4.

  • The oxidation of aldehydes to carboxylic acids can be done by the two-step process.  
  • In the first step, one molecule of water is added in the presence of a catalyst that is acidic.
  • There is a generation of a hydrate. (geminal 1,1-diol).

     CH_3CHO  →  CH_3CH_2COOH [reduction by the gain of electrons]

Here, the oxidizing agent used isCr_3O in the presence of acetone.
