SUMMARY

Salts are defined as ionic compounds, and they always contain ionic bonds, even if their constituents include covalently bonded components. The reaction between an acid and a base results in the formation of a salt through ionic bonding. While many salts are soluble in water, there are notable exceptions, such as barium sulfate, which has very low solubility. Acids and bases exhibit varying solubility in both polar and non-polar solvents, with the general rule being that they are soluble in polar solvents like water.

PREREQUISITES
  • Understanding of ionic and covalent bonding
  • Knowledge of acid-base reactions and neutralization
  • Familiarity with solubility rules in chemistry
  • Basic concepts of polar and non-polar solvents
NEXT STEPS
  • Research the solubility of various salts, focusing on exceptions like barium sulfate
  • Study the properties of polar vs. non-polar solvents in relation to solubility
  • Explore the definitions and classifications of acids and bases in chemistry
  • Learn about the ionization process of salts in water and its implications
USEFUL FOR

Chemistry students, educators, and professionals interested in understanding the properties of salts, acids, and bases, as well as their behavior in different solvents.

Does a salt always have an ionic bond in it regardless of whether it's constituents are covalently bonded or not? When an acid reacts with a base does it always create a salt by means of ionic bonding? I hear all salts are soluble in water but bases are not. What about acids. Are acids soluble in polar or non polar solvents? Also do salts always ionize when dissolved in water?

Salts are ionic compounds by definition. If it has a complex anion or cation that happens to be covalent, the actual salt itself is still formed by an ionic bond. And yes, the product of an acid-base neutralization reaction is a salt--also by definition. All acids and bases are soluble to some degree in water--otherwise they wouldn't be acids and bases. Salts can be insoluble in water, and this varies widely from stuff like sodium chloride that practically has no limit on its solubility to barium sulfate that dissolves only a very tiny amount.

Water is a polar solvent, so, yes, acids are usually soluble in those. I can't remember how the usually dissolve in non-polar solvents, as pretty much all the rules of solubility I was taught were based on water as the solvent. And yes, salts generally ionize in water--the effect of them dissolving.

What do you mean with "it's constituents"? If the bonds inside a compound are covalent, then the compound is not ionic!

It depends on how you define the word "base"; as is usually defined, yes.

That's wrong, there are many insoluble salts.
but bases are not
Wrong, there are many soluble and many insoluble bases.
What about acids. Are acids soluble in polar or non polar solvents?
They can be soluble as well as insoluble, for both polar and non polar solvents.
Also do salts always ionize when dissolved in water?
Almost always.
