Chemical sedimentary rocks can form through processes such as precipitation, where dissolved minerals in water solidify and accumulate to create rock layers. Another process is evaporation, where water evaporates leaving behind concentrated minerals that eventually form into rock.
Physical precipitation of gypsum due to the evaporation of seawater produces sedimentary rock called gypsum rock or rock gypsum.
The main sub-categories of sedimentary rocks are clastic, chemical, and organic. Clastic sedimentary rocks form from the accumulation and cementation of fragments of pre-existing rocks. Chemical sedimentary rocks form from the precipitation of minerals from water solutions. Organic sedimentary rocks form from the accumulation and compression of organic materials, such as plant or animal remains.

Evaporation removes water from sediment to form sedimentary rock. When water evaporates everything that was in the water dries out. The evaporation of water from sediment takes a very long time to form sedimentary rock.

The sedimentary rock formed from minerals precipitating from a solution is called chemical sedimentary rock. It is formed through processes such as evaporation or chemical reactions, without the involvement of organic material or clastic particles.
This is just a guess, but, as the water evaporates, the solution becomes more concentrated with the chemical. More of the chemical would sink to the bottom of the body of water and eventually form sedimentary rock.

Chemical sedimentary rocks, such as limestone and salt rocks, form from minerals dissolved in water that accumulate and solidify through processes like evaporation or precipitation. These rocks are typically composed of minerals that were previously dissolved in water and then re-crystallized to form solid rock.
Limestone is a sedimentary rock that forms as a result of chemical processes. It is composed primarily of calcite or aragonite minerals, which precipitate out of solution in bodies of water. Over time, these deposits solidify to form the limestone rock.

Chemical (or non-clastic) sedimentary rock.
When minerals crystallize from a solution
Chemical sedimentary rock is created by precipitation of minerals out of, or evaporation from, saturated solutions that are high in dissolved minerals. Rock gypsum and rock salt are two examples.
