Van Der Waals Forces: Types & Explanation

AI Thread Summary
Van der Waals forces specifically refer to the intermolecular forces that act between uncharged molecules and do not include covalent or ionic bonds. These forces encompass dipole-dipole interactions, dipole-induced dipole interactions, and induced dipole-induced dipole interactions, commonly known as London dispersion forces. While hydrogen bonds can be categorized as a type of dipole-dipole interaction, they possess distinct properties that warrant their classification as a separate type of intermolecular interaction, distinct from van der Waals forces.

Is Van Der Waals forces just a name for all intermolecular forces that exist between molecules or does it only refer to certain types of intermolecular forces?

All intermolecular forces.
 
What about hydrogen bonds?

van der Waals forces generally refer to intermolecular forces between two separate uncharged molecules (so this excludes covalent and ionic bonding). These forces include dipole-dipole interactions, dipole-induced dipole interactions, and induced dipole-induced dipole interactions (London dispersion forces). Although hydrogen bonds can be thought of as a class of dipole-dipole interactions, their properties are usually different enough that they are considered a class of intermolecular interactions separate from the van der Waals forces.

Thanks.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
