What are the main factors that affect solubility?

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.

What makes a polymer soluble?

Water-soluble polymers are substances that dissolve, disperse, or swell in water and, thus, modify the physical properties of aqueous systems in the form of gelation, thickening, or emulsification/stabilization [25].

What factors affecting solubility of gases in liquids?

The gas solubility in liquids is greatly affected by temperature and pressure as well as the nature of the solute and the solvent.

How does the type of solvent affect solubility?

Solute-Solvent Interactions Affect Solubility Strong solute-solvent attractions equate to greater solubility while weak solute-solvent attractions equate to lesser solubility. In turn, polar solutes tend to dissolve best in polar solvents while non-polar solutes tend to dissolve best in non-polar solvents.

What factors affect solubility quizlet?

Terms in this set (4)

  • Solubility. The solubility of a solution is the maximum quantity of solute that can be dissolved in.
  • Nature of solute and Solvent. Polar solvents generally dissolve polar solutes very well.
  • Temperature. The higher the temperature of the solvent, the greater the solubility of the solute.
  • Pressure.

How does structure affect solubility?

Two substances whose molecules have very similar structures and consequently similar intermolecular forces will usually be soluble in each other. The greater the difference in molecular structure (and hence in intermolecular attractions), the lower the mutual solubility.

What are insoluble polymers?

Polymers, such as polyvinyl formal (PVF) and polyvinyl acetate (PVAc), which are insoluble in water, dissolved in anionic surfactant solution. The polymer forms a complex with the surfactant, the behavior of which is similar to that of polyelectrolyte. The complex is negatively charged and migrates to the anode.

What factors affect the dissolving process?

The rate of dissolution, in contrast, is a measure of how fast a solute dissolves in a solvent. There are three factors that affect the rate of dissolution: (1) the surface area of the solute, (2) the temperature of the solvent, and (3) the amount of agitation that occurs when the solute and the solvent are mixed.

How does solubility affect dissolution rate?

Solubility and dissol ution rate are two distinct phenomena. Dissolution rate is a kinetic process. A solute may have poor solubility in a solvent, yet its dissolution rate may be rapid. Conversely, a solute can be very soluble, yet require a protracted amount of time to arrive at the final, saturation concentration.

What factors affect solubility of ionic compounds?

– Hence, we can conclude that the four factors which affect the solubility of ionic compounds are common ion effect, temperature, solute-solvent interaction and molecular size.
