Define the problem

Explanation:

The first step in a scientific investigation is to define the problem at hand. Definition of a scientific problem makes a scientific investigations possible.

  • When preliminary observations are made about a phenomenon. A lot of questions as to why such things occur will arise.
  • From the question, we can state the problem and the likely causes.
  • The first portal in an inquiry is problem definition.
  • This would them lead to the formulation of a hypothesis which contains problem statement and likely causes.
  • The hypothesis leads to the design of an experiment from which investigations using experiments can be done.
  • The data from the experiments are collected and analyzed.

Provide an explanation that is grounded in polarity that better explains why oil is not miscible in vinegar.
butalik [34]

Explanation:

Vinegar is a sour liquid made up of acetic acid compounds. Oil is a complex non-polar chemical compound with a high amount of hydrogen and carbon in its structure.

  • Vinegar is a polar acid, although a weak one.
  • Generally, for a substance to mix with another one, they must be similar.
  • Solubility of compounds controls miscibility.
  • When two substances are miscible, they can be said to be soluble in one another.
  • In solubility, like substances dissolves like substances.
  • This implies that polar compounds will only dissolve polar compounds.
  • Non-polar compounds will only dissolve in non-polar solvents.
  • Since vinegar is polar and oil is non-polar, they will not dissolve one another.
