Colloids

21.2K
Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Lewis Structures and Formal Charges

22.5K
Lewis symbols can be used to indicate the formation of covalent bonds, which are shown in Lewis structures—drawings that describe the bonding in molecules and polyatomic ions. The periodic table can be used to predict the number of valence electrons in an atom and the number of bonds that will be formed to reach an octet. Group 18 elements, such as argon and helium, have filled electron configurations and thus rarely participate in chemical bonding. However, atoms from group 17, such as...

Formal Charges

40.6K
In some cases, there are seemingly more than one valid Lewis structures for molecules and polyatomic ions. The concept of formal charges can be used to help predict the most appropriate Lewis structure when more than one reasonable structure exists.

Trends in Lattice Energy: Ion Size and Charge

26.8K
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a measure of the strength of this attraction. The lattice energy (ΔHlattice) of an ionic compound is defined as the energy required to separate one mole of the solid into its component gaseous ions. For the ionic solid sodium chloride, the lattice energy is the enthalpy change of the process:

Range00:59

Range

14.3K
The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in the study of seven 16-ounce soda cans, the filled volume of soda was measured, thus producing the following amount (in ounces) of soda:
15.9; 16.1; 15.2; 14.8; 15.8; 15.9; 16.0; 15.5
Measurements of the amount of soda in a 16-ounce can vary since different subjects record these measurements or since the exact amount - 16 ounces of liquid, was not...

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles visible to the naked eye or seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. The suspended particles in a suspension settle out after some time of mixing. The separation of particles from a suspension is...

Area of Science:

  • Colloid and Surface Science
  • Statistical Mechanics
  • Computational Physics

Background:

  • Theoretical and simulation studies of charged suspensions typically focus on infinite dilution, examining isolated particle interactions.
  • Experimental studies on latex particle solutions suggest the presence of very-long-range correlations in charged macroion systems.
  • Existing models often do not fully capture the complex phenomenology observed in concentrated charged suspensions.

Purpose of the Study:

  • To investigate the electrolyte structure and charge distribution in charged macroion suspensions at finite volume fractions using integral equation theory.
  • To identify and characterize novel charge inversion phenomena beyond the scope of infinite dilution models.
  • To compare theoretical predictions with simulation and experimental data for validation.

Main Methods:

  • Application of integral equation theory to a model of charged macroions at finite volume fraction.
  • Development of a theoretical framework to describe electrolyte structure and correlations.
  • Comparison of theoretical results with data from Monte Carlo simulations and existing experimental findings.

Main Results:

  • Discovery of an amplitude-modulated charge inversion structure with outsized amplitudes and very-long-range extension.
  • Observation that these charge inversions occur at finite macroion volume fractions and are distinct from standard inversions.
  • Demonstration that inversion amplitude increases with particle charge and distance, indicating strong long-range correlations.

Conclusions:

  • The integral equation theory successfully predicts novel, long-range charge inversion phenomena in charged macroion suspensions.
  • These findings highlight the importance of considering finite volume fractions for understanding complex correlations in charged colloidal systems.
  • The results are consistent with Monte Carlo simulations and qualitative experimental observations, supporting the validity of the model.
