Common Forms That Dissolve in Liquids:
* Solids:
* Salts: Table salt (NaCl), sugar (sucrose), potassium chloride (KCl)
* Acids: Citric acid, acetic acid (vinegar), hydrochloric acid (HCl)
* Bases: Sodium hydroxide (NaOH), potassium hydroxide (KOH)
* Metals: Some metals, like sodium and potassium, react vigorously with water to dissolve.
* Other solids: Many solids like gelatin, starch, and some polymers can dissolve or form suspensions in liquids.
* Liquids:
* Alcohols: Ethanol, methanol
* Acids: Nitric acid, sulfuric acid
* Bases: Ammonia solution
* Other liquids: Miscible liquids, like water and ethanol, can dissolve completely in each other.
* Gases:
* Carbon dioxide: Dissolves in water to create carbonic acid.
* Oxygen: Dissolves in water, though not very much.
* Nitrogen: Dissolves in water, but even less than oxygen.
Factors Affecting Dissolution:
* Solubility: The ability of a solute to dissolve in a solvent is called solubility. It's influenced by factors like:
* Polarity: "Like dissolves like". Polar solutes (like sugar) tend to dissolve in polar solvents (like water), while non-polar solutes (like oil) dissolve in non-polar solvents (like gasoline).
* Temperature: Solubility often increases with temperature.
* Pressure: For gases, solubility increases with pressure.
* Intermolecular forces: Stronger interactions between solute and solvent molecules lead to higher solubility.
Important Note:
* Not all substances dissolve in all liquids. For example, oil won't dissolve in water because they have different polarities.
* The process of dissolving involves the formation of new bonds between solute and solvent molecules.
