Students will be able to plan and carry out an investigation to compare the solubility of different substances, and develop and explain a particle-level model to describe the process of dissolving.

The solubility of any given substance—the measure of how well the substance dissolves into another substance referred to as the solvent—depends on basic properties like temperature and pressure, as ...

In a world first, researchers have recorded exactly how solvents interact with dissolved materials, one atom at a time. After a solute, such as salt, dissolves in a solvent, such as water, the two ...

Dissolved black carbon, a water-soluble fraction of black carbon produced from incomplete combustion and biochar, has long been viewed as a mobile ...

Primary production by phytoplankton represents a major pathway whereby atmospheric CO 2 is sequestered in the ocean, but this requires iron, which is in scarce supply. As over 99% of iron is complexed ...

Introduction Have you ever added a spoon of sugar to your tea and wondered why it disappeared? Where did it go? The sugar did not actually disappear—it changed from its solid form into a dissolved ...

Despite the importance of predicting solubility, it is not an easy matter. One approach, using 'brute force' simulations, requires long computing times. Other techniques, while faster, fail to predict ...
