Grain size characterization of siliciclastic sedimentary and sedimentary rocks Sediment sorting and mineralogy can also be used to name siliciclastic sedimentary rocks, particularly sandstones. If a sandstone contains little silt and clay (e.g., less than 15% by volume), it is said to be an arenite.
A: Chemical dissolution is when a solute contacts a solvent and forms a solution by dissolving. Dissolution is the reverse of the precipitation process, and the two processes form a dynamic equilibrium. The precipitation of a solid form or the evolution of gas occurs when evaporation or another process removes the solvent from the solution.
To dissolve is defined as to become broken up or absorbed by something or to disappear into something else. 1  When sugar becomes absorbed into water, this is an example of when sugar dissolves into water. 2  When a club breaks up and the members go their separate ways, this is an example of a time when the club dissolves.
