Water dissolves many substances. Why does this occur?

Answer 1

Well, water is a #"protic, polar solvent............"#

Water is a highly unusual liquid. It has low molecular mass, yet very high normal boiling point. The high boiling point owes to extensive, intermolecular hydrogen bonding in the bulk liquid. We can represent the polarity of water by a diagram of the form #""^(delta+)H-O^(delta-)-H^(delta+)#, and this polarity, this charge separation allows water to solvate ions effectively. Most substances, polar or ionic or not, have some water solubility.

Water is a polar molecule, meaning it has a positive and negative end. This polarity allows water molecules to attract and surround other charged or polar molecules, breaking them apart and dissolving them. This process is called hydration or solvation. Additionally, water's ability to form hydrogen bonds further enhances its dissolving power.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
