There must exist a solvent for the substance to be extracted in which this substance's solubility is greater than the substance's solubility in water, and the solvent also must not be miscible in water, so that an interface between the solvent and water will be formed in a mixture of the two.

Steps for the preparation of a standard solution?
1. Weigh the necessary substance 2. Put this substance in a bottle or Berzelius, Erlenmeyer flask. 3. Add slowly the adequate volume of solvent and stir. 4. Apply a label (date, name of the operator, name of the solution, concentration, etc.).
The substance that dissolves in the solvent in a solution?

Is it necessary for every compound to be acidic or basic or neutral?
To measure the pH of a substance it has to be in solution so if the substance is insoluble you cannot measure its pH. A basic substance is not the same as an alkaline substances. A basic substance is one which can neutralise an acid. An alkaline substance is a solution of a base. For example, chalk (calcium carbonate) is basic as it neutralises acids but as it is insoluble, it is not an alkali. However solid sodium hydroxide can be described as a base as it can neutralise an acid and as it is soluble in water, a solution of sodium hydroxide is both a base and an alkali.
Why volume of toluene decrease after extraction?
It may trapped in your sample, if it's a polymer for example. Or it may reacted with a substance in the solution.
