How and why does electronegativity influence solubility? Scientists solve the mystery behind an enigmatic organelle, the pyrenoid ; A hint of new … Understanding the solubility of polysaccharides is extremely important for their food applications as most functions of polysaccharides including stability, emulsifying property, drug delivery, membrane forming properties, etc., are all achieved in aqueous solution. The particle/particle interactions in the solid state must be broken and energy must be pumped in to accomplish this. In general an increase in temperature should result in an increase in solubility. It doesn’t affect solubility — which is an equilibrium process — but it does affect the rate of dissolution. In general, solubility of a gas in water will decrease with increasing temperature: colder water will be able to have more gas dissolved in it. Surface area does not affect how much of a solute will be dissolved, but it is a factor in how quickly or slowly the substance will dissolve. Sometimes, of course, an increase in temperature does not result in increased solubility. In this section, we will explore all three of these factors and how they affect the solubility of solids and gases. This chapter aims specifically at the mechanism of solubility of polysaccharides from the molecular level. K Honeychurch 1K Posts: 27 Joined: Fri Sep 26, 2014 9:02 pm. I've spent the past half an hour reading lumenlearning and libretexts, but haven't found anything that substantially answers my question. Top. I need to answer this question with several examples and include structural diagrams. = ) Thanks in advance! The Effect of Temperature on Solubility Temperature has a direct effect on solubility. Specifically in biochemistry. You won’t get more solute into solution with stirring than you will without, but you’ll get it dissolved a lot faster. 78. Use electronegativities to predict which of the following compounds is more soluble in water: a) LiI or MgI2; b) CaS or CaO. I do know that a globular protein has increased solubility while a fibrous protein has decreased solubility. In questions 77 and 78, it is asked to determine which of two compounds is more soluble in water. What I'd like to know is HOW and WHY does the globular and fibrous structure affect the protein's solubility. What features in the molecular structure of a compound affect its solubility and its melting and boiling points.

How do functional groups affect the structure, solubility, and reactivity of macromolecules and their subunits? Dissolution is a bond breaking reaction. Several factors affect the solubility of gases: one of these factors is temperature.
