The equation that describes the equilibrium between solid calcium carbonate and its solvated ions is:

Solution Equilibrium and Saturation

Solution Equilibrium and Saturation

Imagine adding a small amount of sugar to a glass of water, stirring until all the sugar has dissolved, and then adding a bit more. You can repeat this process until the sugar concentration of the solution reaches its natural limit, a limit determined primarily by the relative strengths of the solute-solute, solute-solvent, and solvent-solvent attractive forces. You can be certain that you have reached this limit because, no matter how long you stir the solution, undissolved sugar remains. The...

Summary

Ink spreading on paper shows a multiaffine interface. Interface roughness exponents depend on paper orientation, but the growth exponent remains consistent, revealing insights into spontaneous imbibition dynamics.

Background:

Spontaneous imbibition is a fundamental process in porous media, crucial for applications like printing and fluid absorption.
Understanding the ink-paper interface dynamics is key to controlling fluid spreading and pattern formation.

Purpose of the Study:

To investigate the behavior of the ink-paper interface during spontaneous imbibition.
To characterize the interface roughness as a function of time and paper orientation.
To determine the multiaffine nature of the interface evolution.

Main Methods:

Conducted spontaneous imbibition experiments with ink on paper.
Quantified interface roughness using growth (beta) and Hurst (H) exponents derived from the root mean square interface width (W).
Analyzed the qth order height-height correlation function to calculate the H{q} scaling exponent.

Main Results:

The Hurst (H) and H{q} scaling exponents were found to be dependent on the orientation of the paper sheets.
The growth exponent (beta) showed no dependence on paper orientation.
The ink-paper interface consistently exhibited multiaffine characteristics throughout the imbibition process.

Conclusions:

Paper orientation significantly influences the statistical properties of the ink-paper interface during spontaneous imbibition.
The observed multiaffine behavior suggests complex, orientation-dependent growth dynamics at the interface.
These findings contribute to a deeper understanding of fluid transport in anisotropic porous media.
