Answer:
A. increasing the temperature
Explanation:
The solutions are dispersed systems formed by the mixture of two or more substances, homogeneous and of variable composition within certain limits.
The solution is constituted by the solute (component that is in smaller proportion and that is the one that disperses) and solvent (component that is in greater proportion where the solute is dispersed).
Aqueous solutions allow the occurrence of many essential processes for life, agriculture and industry.
The dissolution process is a spontaneous process, but we can perform some actions to increase the dissolution rate of a solid solute in the solvent. These are:
1- Shake
2- Warm up
3- Shred
By stirring the solute and the solvent, diffusion of the particles is favored and the dissolution rate increases.
By increasing the temperature by heating, the particles of the solute and the solvent correspond to a greater energy, the frequency of the shocks between them increases, and as a consequence, the dissolution rate increases.
Crushing a solid increases its total area of the solid that is crushed and therefore the possibility of contact with the substances that participate in the dissolution process is greater.
In summary, the factors that increase the dissolution rate of a solid in a liquid are:
1- agitation
2- the temperature
3- the contact surface
The solutions are also classified in unsaturated solution which is the one that allows dissolving more solute at a given temperature and in saturated solution is the one that does not admit dissolving more solute at a given temperature.
