The polar nature of <a data-lesson="unique-properties-of-water" data-subject="chemistry" data-tutorial="states-of-matter" href="https://app.ulearngo.com/chemistry/states-of-matter/unique-properties-of-water">water</a> means that ionic compounds dissociate easily in aqueous solution into their component ions.
</li>
<li>
Dissociation is a general process in which <a data-lesson="ionic-solids" data-subject="chemistry" data-tutorial="liquids-and-solids" href="https://app.ulearngo.com/chemistry/liquids-and-solids/ionic-solids">ionic</a> <a data-lesson="compounds-2" data-subject="chemistry" data-tutorial="quantitative-aspects-chemical-change" href="https://app.ulearngo.com/chemistry/quantitative-aspects-chemical-change/compounds-2">compounds</a> separate into smaller ions, usually in a <a data-lesson="reversible-reactions" data-subject="chemistry" data-tutorial="chemical-equilibrium" href="https://app.ulearngo.com/chemistry/chemical-equilibrium/reversible-reactions">reversible</a> manner.
</li>
<li>
Dissolution or dissolving is the process where ionic crystals break up into ions in water.
</li>
<li>
Hydration is the process where ions become surrounded with water molecules.
</li>
<li>
Conductivity is a measure of a solution's ability to conduct an electric current.
</li>
<li>
An electrolyte is a substance that contains free ions and is therefore able to conduct an electric current. Electrolytes can be divided into strong and weak electrolytes, based on the extent to which the substance ionises in solution.
</li>
<li>
A non-electrolyte cannot conduct an electric current because it does not contain free ions.
</li>
<li>
The type of substance, the concentration of ions and the temperature of the solution affect its conductivity.
</li>
<li>
There are three main types of <a data-lesson="reactions-2" data-subject="chemistry" data-tutorial="metals-metalloids-nonmetals" href="https://app.ulearngo.com/chemistry/metals-metalloids-nonmetals/reactions-2">reactions</a> that occur in aqueous solutions. These are precipitation reactions, <a data-lesson="acid-base-reactions-3" data-subject="chemistry" data-tutorial="acid-base-redox-reactions" href="https://app.ulearngo.com/chemistry/acid-base-redox-reactions/acid-base-reactions-3">acid-base reactions</a> and redox reactions.
</li>
<li>
Precipitation and acid-base reactions are sometimes known as ion exchange reactions. Ion <a data-lesson="other-types-of-reactions" data-subject="chemistry" data-tutorial="reactions-in-aqueous-solution" href="https://app.ulearngo.com/chemistry/reactions-in-aqueous-solution/other-types-of-reactions">exchange reactions</a> also include <a data-lesson="non-ideal-gas-behavior" data-subject="chemistry" data-tutorial="gases" href="https://app.ulearngo.com/chemistry/gases/non-ideal-gas-behavior">gas</a> forming reactions. Ion exchange reactions are a type of reaction where the positive ions exchange their respective negative ions due to a driving force.
</li>
<li>
A precipitate is formed when ions in solution react with each other to form an insoluble product. Solubility rules help to identify the precipitate that has been formed.

A <a data-lesson="atomic-and-atomic-mass-number" data-subject="chemistry" data-tutorial="chemistry-essential-ideas" href="https://app.ulearngo.com/chemistry/chemistry-essential-ideas/atomic-and-atomic-mass-number">number</a> of tests can be used to identify whether certain anions (chlorides, bromides, iodides, carbonates, sulphates) are present in a solution.
</li>
<li>
An acid-base reaction is one in which an acid reacts with a base to form a <a data-lesson="acid-base-reactions-continued-2" data-subject="chemistry" data-tutorial="acid-base-redox-reactions" href="https://app.ulearngo.com/chemistry/acid-base-redox-reactions/acid-base-reactions-continued-2">salt</a> and water.

Summary and Main Ideas

Chemistry generally explores the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances. 

Chemistry

Explore how different substances dissolve and react with each other in water, including ionization and conductivity, precipitation reactions, tests for anions, and various types of reactions such as redox and ion exchange.
