Chemical Weathering Processes

Chemical weathering of rocks is largely responsible for the creation of soil. Along with physical disintegration of rocks, chemical processes involve the breakdown of minerals by acids of various kinds.

Weathering transforms a proportion of solid particles into clay and water-soluble forms of minerals, leaving a mixture that has a smaller proportion of solids.

Water and air (oxygen and carbon dioxide) along with heat must be present to speed up all chemical reactions.

Solution When something is dissolved in water or acids, the water or acid with dissolved contents is called solution.

This process involves removal of solids in solution and depends upon solubility of a mineral in water or weak acids. On coming in contact with water many solids disintegrate and mix up as suspension in water.
