Solute and Solvent

Answer:

The solute in the Alcohol-Water solution is letter B which is water.

Explanation:

In the above given  Alcohol-Water solution, the solute is Water. Although water is the universal solvent in this case, given that alcohol and water is in the same phase as well as the amount of alcohol is greater than water; This means that water is being dissolved in alcohol.

Further in formation on Solutions, Solute and Solvent:

A Solution has the following characteristics:

  • Homogenous mixture of two or more substances. (homogenous mixtures means that the molecules of the solution is evenly mixed)
  • Exists in any phase (solid, liquid or gas)
  • A type of mixture that can not be separated by mechanical means like (sifting, screening or filtering)

Example of Solutions per phase

  • gas / gas ->  mixture of nitrogen and oxygen -> air
  • gas / liquid ->  mixture of water and carbon dioxide -> soda
  • liquid/ liquid ->  mixture of alcohol and water -> alcohol solution
  • solid/ liquid ->  mixture of water and salt -> sea water

Types of solution per concentration

  • Unsaturated Solution - more solute dissolves
  • Saturated Solution - no more solute dissolves
  • Supersaturated Solution - unstable solution, crystals form

A Solute has the following characteristics:

  • It is the minor component in a solution.
  • It is the one being dissolved in a solution.

A Solvent has the following characteristic:

  • It has the part of the solution where the solute is dissolved.
  • Water is the universal solvent.
