Understanding Dissolution Basics

Dissolution is the process by which a solute forms a solution by breaking down into individual ions, atoms, or molecules that disperse throughout a solvent. It occurs when a solid or liquid substance mixes homogeneously within a solvent. Key factors that affect the dissolution rate include the polarity of the solute and solvent, surface area of the solute, and temperature - with greater surface areas and higher temperatures typically increasing the rate.

Dissolution

To completely mix with and become part of another substance.


Dissolution is the process by which a substance forms a solution in a solvent (A
solute is the primary substance that is dissolved in a liquid called the solvent.). For the
dissolution of solids, the process of dissolution can be explained as the breakdown
of the crystal lattice into individual ions, atoms or molecules and their transport into
the solvent. Dissolving is when the solute breaks up from larger crystal of molecules
into much smaller groups or individual molecules. This break up is caused is caused
by coming into contact with the solvent.

-Dissolution is defined as the rate of mass transfer from a solid surface into the dissolution
medium or solvent under standardized conditions of liquid/solid interface, temperature and
solvent composition. It is a dynamic property that changes with time and explains the
process by which a homogenous mixture of a solid or a liquid can be obtained in a solvent.
It happens to chemically occur by the crystal break down into individual ions, atoms or
molecules and their transport into the solvent.
- Is the process of dissolving various substances in a medium like water

My Explanation

When a solute in a solvent forms a solution, it is called dissolution. A solute is the primary


substance that is dissolved in a liquid called the solvent. So, what this means is that it is
when something dissolves in something else.

There are many factors that affect the rate at which a solute will dissolve. The general rule is
that 'like dissolves like.' This means that a polar substance will dissolve in another polar
substance - and non-polar in non-polar. Solid substances with greater surface areas dissolve
faster than solid substances with smaller surface areas. In general, solids dissolve faster
with increased temperature. The solubility of gas depends on pressure and temperature.

Greater surface areas of solids help them dissolve faster. The only place that dissolution can
take place is at the surface of a solid. Therefore, it stands to reason that the greater surface
area available, the faster the substance will dissolve.
