Typiske sterke baser er baser basert på <a href="/wiki/Hydroksid" title="Hydroksid">OH<sup>–</sup>-ioner</a>, for eksempel <a href="/wiki/Natriumhydroksid" title="Natriumhydroksid">NaOH (natriumhydroksid)</a> (også kjent som <i><a href="/wiki/Kaustisk_soda" class="mw-redirect" title="Kaustisk soda">kaustisk soda</a></i> eller <i>natronlut</i>) eller <a href="/wiki/Kalsiumhydroksid" title="Kalsiumhydroksid">Ca(OH)<sub>2</sub> (kalsiumhydroksid)</a>. Alle sterke baser har en korresponderende <i>svak syre</i> (se <a href="#Syre-base-par">Syre-base-par</a>). </p><p>En base klassifiseres som <i>svak</i> når protolysegraden er mindre enn 5%.
