Factors Affecting Solubility

Factors Affecting Solubility

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Assembly of the Lipid Bilayer in the ER

Assembly of the Lipid Bilayer in the ER

Biological membranes are more than just a barrier separating cell cytoplasm from the outside environment. They are highly dynamic and help maintain the integrity and physiological stability of the cells as well as membrane-bound organelles. Membranes also play vital roles in cell-to-cell and intracellular communication.
A large chunk of any biological membrane is composed of phospholipids. These lipids have a heterogeneous distribution across different subcellular organelles and even between...

Acid Suppressive Drugs for Peptic Ulcer Disease: Antacids

Acid Suppressive Drugs for Peptic Ulcer Disease: Antacids

In the complex environment of the gastric lumen, excessive acid secretion can lead to the formation or worsening of ulcers within the delicate mucosal layer. Antacids, such as sodium bicarbonate and calcium carbonate, provide relief by neutralizing this acid, transforming it into harmless salt and water. This neutralization process raises the gastric pH from a highly acidic level of 1 to a more basic 3-4, reducing the acidity within the stomach.
However, this neutralization reaction between...
