Solubility Equilibria: Ionic Product of Water01:16

Solubility Equilibria: Ionic Product of Water

Pure water is a weak electrolyte; only a small amount ionizes into hydrogen and hydroxide ions. At any given temperature, the concentration of undissociated water is almost constant, so the ionic product of water is the product of the hydrogen and hydroxide ion concentrations, denoted as Kw. The square root of Kw gives the individual ion concentrations.
The ionic product of water varies with temperature, and its value is 1.0 x 10−14 at standard experimental conditions. Per Le Chatelier's...
Porosity and Absorption of Aggregate01:20

Porosity and Absorption of Aggregate

Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the aggregate...
Adsorption Isotherms I01:29

Adsorption Isotherms I

Adsorption isotherms are mathematical models that describe how molecules in a gas or liquid phase interact with surfaces. Two of the most common isotherm models are the Langmuir and Freundlich isotherms, which relate to Type I monolayer chemisorption. The Langmuir model is based on four key assumptions:• Adsorption cannot exceed monolayer coverage.• All surface sites are equivalent.• Molecules adsorb only at vacant sites.• There are no interactions between adsorbed molecules.Consider the...

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model

Various dissolution theories provide insight into the factors that influence the dissolution rate. Danckwerts' Model suggests that turbulence, rather than a stagnant layer, characterizes the dissolution medium at the solid-liquid interface. In this model, the agitated solvent contains macroscopic packets that move to the interface via eddy currents, facilitating the absorption and delivery of the drug to the bulk solution. The regular replenishment of solvent packets maintains the concentration...
Adhesion01:14

Adhesion

Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow glass...
Adsorption of Gases on Solids01:28

Adsorption of Gases on Solids

Adsorption is a process where molecules, known as the adsorbates, accumulate on a surface, which is referred to as the adsorbent or substrate. Occurring at the solid-gas interface, this phenomenon is crucial in various scientific and industrial contexts. The reverse of adsorption is desorption.Two types of adsorptions exist: physical (physisorption) and chemical (chemisorption). Physisorption involves gas molecules held to the solid's surface by relatively weak intermolecular van der Waals...

Summary

Water adsorption on calcium silicate surfaces forms distinct structures based on coverage. At low densities, water follows the surface lattice, but higher coverages lead to complex patterns and cluster formation.

Area of Science:

  • Surface Science
  • Materials Chemistry
  • Physical Chemistry

Background:

  • Water adsorption on silicate surfaces is crucial for mineral weathering and cement hydration.
  • Understanding these interactions at an atomic level is essential for predicting material behavior.

Purpose of the Study:

  • To investigate the atomic-scale structure of water overlayers on a model calcium silicate surface (wollastonite).
  • To elucidate the interplay between water-surface and water-water interactions at varying coverages.

Main Methods:

  • Atomically resolved non-contact atomic force microscopy (nc-AFM) in ultrahigh vacuum.
  • Density functional theory (DFT) calculations using the r2SCAN + rVV10 functional.

Main Results:

  • At low water coverage (2 molecules/unit cell), water adsorbates follow the wollastonite (100) surface lattice.
  • Increased coverage leads to competition between hydrogen bonding and surface interactions, forming complex patterns.
  • Above 4 molecules/unit cell, water-water interactions dominate, resulting in cluster formation.

Conclusions:

  • The study provides an atomic-scale framework for water interactions with calcium silicate surfaces.
  • Experimental symmetries aid in constraining theoretical structural models.
  • The findings are relevant to geological processes and material science applications.
