SWS3022 Lectures 15 Exam Questions and Answers 100% Pass organic chemical - also referred to as an organic compound, is defined as being constructed of molecules that possess carbon-based atoms. Specifically, it is composed of carbon atoms attached to hydrogen atoms, together with a variety of other elements from functional groups, such as oxygen, nitrogen, sulfur, etc. Usually, an organic chemical is covalently bonded, meaning that electrons are shared between atoms. This characteristic is why organic chemicals can be structured in a variety of long chains and rings and form bonds with the great stability. Can be naturally-occurring or synthetic in nature. Inorganic solution constituents may contain carbon, but are not based generally on the carbon atom. - Metals Chemical Nutrients Acids Some Inorganic Chemicals in Soil Solution - Na+, K+, Ca2+, Mg2+, Cu2+, Fe3+ 2Katelyn Whitman, All Rights Reserved © 2025 Cl-, Br-, F-, I- NO3-, CO32-, SO42-, PO4-3 Cd2+, Pb2+ Hg2+ AsO4-3 H+ Ion - Ions are stable forms of elements that acquire an electrical charge by gaining or losing electrons Ions are stable forms of elements that acquire an electrical charge by gaining or losing electrons cations - Elements that lose electrons and become positively charged anions - Elements that gain electrons and become negatively charged Origins of Dissolved Ions in Soil Solution - Mineral Weathering Breakdown of Organic Matter Ions from O.M. breakdown and weathering establish electrostatic bonds with Water. 3Katelyn Whitman, All Rights Reserved © 2025 Water molecules have the ability to orient themselves relative to the introduction of a solute. - true Ion hydration - Orientation of Water Molecules Hydration Sphere The size of the hydration sphere determines the size of the ion in solution.
