RSD stands for Relative Standard Deviation and is a measure of the variability of a sample compared to its mean.
RSD is calculated by dividing the standard deviation of a sample by its mean and multiplying by 100.
It is expressed as a percentage and is often used in analytical chemistry to assess the precision of a method.
A low RSD indicates that the data is precise and consistent, while a high RSD indicates that the dat...

Dissolution is the process by which a solid substance dissolves in a solvent to form a solution.
The first stage is the wetting stage, where the solid substance comes into contact with the solvent.
The second stage is the dissolution stage, where the solid substance dissolves in the solvent.
The third stage is the diffusion stage, where the dissolved substance diffuses away from the solid surface into the bulk of the solv...
