Phase Transitions: Sublimation and Deposition02:33

Phase Transitions: Sublimation and Deposition

Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...
Intermolecular Forces in Solutions02:28

Intermolecular Forces in Solutions

The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without energy from some external source.
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Physical Properties Affecting Solubility

Solutions of Gases in Liquids
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
Formation of Complex Ions03:45

Formation of Complex Ions

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...
Ionic Strength: Effects on Chemical Equilibria01:19

Ionic Strength: Effects on Chemical Equilibria

The addition of an inert ionic compound increases the solubility of a sparingly soluble salt. For example, adding potassium nitrate to a saturated solution of calcium sulfate significantly enhances the solubility of calcium sulfate. Le Châtelier's principle cannot predict this shift in the equilibrium. Instead, this could be explained in terms of changes in the effective concentration of the ions in solution in the presence of added inert salt.
In this solution, the primary cation—the calcium...
Solubility Equilibria: Overview01:09

Solubility Equilibria: Overview

When a substance such as sodium chloride is added to water, it dissolves, forming an aqueous solution. The extent of dissolution is called solubility. The process of dissolution can exist in equilibrium, just like other chemical processes. Solubility equilibria are also called precipitation equilibria because the process of solubility can be reversible. The reverse of the solubility process is called precipitation.
Solubility is important in biological and environmental processes. A notable...

Summary
This summary is machine-generated.

Experiments reveal that subduction zone fluids interacting with silicates can hold significantly more dissolved carbon dioxide (CO2) than previously estimated. This finding impacts models of deep carbon transfer in Earth's mantle.

Area of Science:

  • Geochemistry
  • Experimental Petrology
  • Subduction Zone Processes

Background:

  • Estimates of dissolved carbon dioxide (CO2) in subduction zone fluids traditionally rely on limited experimental data and thermodynamic models.
  • Understanding CO2 solubility in deep fluids is crucial for modeling carbon cycles and mantle dynamics.

Purpose of the Study:

  • To experimentally determine the volatile and solute content of graphite-saturated fluids interacting with silicates at subduction zone conditions.
  • To investigate the influence of silicate interactions on CO2 solubility in deep aqueous fluids.

Main Methods:

  • Experimental determination of fluid composition in the systems COH, SiO2-COH, and MgO-SiO2-COH at 1-3 GPa and 800°C.
  • Utilized graphite-saturated conditions to simulate deep Earth environments.
  • Analyzed fluid volatiles and solute contents, including CO2 and water activity.

Main Results:

  • Fluids interacting with silicates showed up to 30 mol% higher CO2 content compared to pure COH systems.
  • A decrease in water activity, likely due to the formation of Si-O-C and Si-O-Mg organic complexes, was observed.
  • Experimental data contradicts sparse previous estimates, highlighting higher CO2 solubility.

Conclusions:

  • The interaction between deep aqueous fluids and silicates represents a significant, previously unrecognized mechanism controlling subduction zone fluid composition.
  • This interaction enhances the transfer of deep carbon from the slab-mantle interface to the overlying mantle wedge, particularly in fluid-rich environments.
  • Novel insights into deep carbon cycling and mantle metasomatism are provided.
