Solucion quimica
Summary
Solucion quimica (solution chemistry) is a homogenous mixture of two or more pure chemical substances. It is characterized by at least two components: a solute (the one dissolved in the other) and a solvent or disolvent (which dissolves the solute). Solutions are classified according to two criteria: the proportion between the solute and the solvent, and the aggregation state of the components. Concentration is a magnitude that describes the proportion of solute to solvent in a solution. It is expressed in physical units (expressed in relation to the weight and volume of the solution, in percentage) and in chemical units (molarity, molality, and molar fraction).
Q&As
What is a chemical solution?
A chemical solution is a homogeneous mixture of two or more pure chemical substances.
What are the characteristics of a chemical solution?
A chemical solution is characterized by having a solute and a solvent (at least) in some detectable proportion, not being able to distinguish its constituent elements by sight, and not being able to separate solute and solvent by physical methods such as filtration or sieving.
How are chemical solutions classified?
Chemical solutions can be classified according to two criteria: the proportion between the solute and the solvent, and the state of aggregation of the components.
What is the concentration of a chemical solution?
The concentration is a magnitude that describes the proportion of solute with respect to the solvent in a solution.
What are the two types of units used to express concentration of a chemical solution?
The two types of units used to express concentration of a chemical solution are physical units and chemical units.

Technical terms
- Solucion quimica
- A homogeneous mixture of two or more pure chemical substances.
- Soluto
- The substance that is dissolved in the other.
- Solvente o disolvente
- The substance that dissolves the solute.
- Diluidas
- When the amount of solute relative to the solvent is very small.
- Concentradas
- When the amount of solute relative to the solvent is large.
- Saturadas
