The solute is the substance dissolved in a solvent. Example: in the salted water sodium chloride is the solute and water is the solvent.
All solutions have a solute (or more) and a solvent.
Solvent
Magnesium can be a solute depending on the conditions, but it is not always one. In aqueous solutions, magnesium metal is not a solute, but magnesium ions can be. In solids, magnesium can be thought of as a solute in certain metal solutions known as alloys. Thus, whether or not magnesium is a solute depends on the context.
This depends on the nature of solvent and solute, concentration of solute, temperature, etc.
less then 0.01M
Solutions that have a small amount of solute.
The solute is dissolved in the solvent to form a solution.
Isotonic solutions have equal amounts of solute and solvent which means that the solution is 50% solute and 50% solvent. Solutions which have more or less solute are called hypotonic and hypertonic.
All solutions have a solute (or more) and a solvent.
Solvent
sometimes. All solutions have at least one solute and one solvent. While water often does act as a solvent, some solutions have other solvents. Solutions where the solute is dissolved in water belong to a special group of solutions called aqueous solutions.
Wood is not a solution. Only solutions have a solvent and a solute.
A solvent and a solute.
Sodium chloride may be a solute in water solutions.
