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.
2. (Chemistry) the act or process of forming a solution. 3. (Chemistry) the state of being dissolved (esp in the phrase in solution) 4. (Chemistry) a mixture of two or more substances in which one or more components are present as small particles with colloidal dimension; colloid: a colloidal solution. 5. a specific answer to or way of answering a problem.
