Natriumsilikat vert brukt mellom anna i maskinoppvaskmiddel. Vanleg såpe er natriumsalt av feittsyrer, og vert framstilt av natriumhydroksid (NaOH) og feitt. </p><p>Sidan natrium reagerer så kraftig med vatn, blir det brukt til å fjerne vatn (tørke) organiske løysemiddel, enten aleine eller saman med kalium. </p><p>Natrium har svært høg elektronegativitet, og natriummetall vil reagere med metallsalt som har høgare elektonegativitet og danne natriumsalt og fritt metall av det andre metallet. Mange metall vart oppdaga ved at ein lét natrium eller kalium reagere med ulike mineral som inneheldt det nyoppdaga metallet. Sjølv om ein kan framstille metall slik, er dette ein dyr metode, og blir berre brukt dersom ein ikkje kjenner til betre metodar. </p> <div class="mw-heading mw-heading2"><h2 id="Viktige_sambindingar">Viktige sambindingar</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Natrium&veaction=edit&section=3" title="Endre bolk: Viktige sambindingar" class="mw-editsection-visualeditor"><span>endre</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Natrium&action=edit&section=3" title="Rediger kildekoden til seksjonen Viktige sambindingar"><span>endre wikiteksten</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/w/index.php?title=Boraks&action=edit&redlink=1" class="new" title="Boraks (sida finst ikkje)">Boraks</a> (Na<sub>2</sub>B<sub>4</sub>O<sub>7</sub>)</li> <li><a href="/wiki/Natriumhydroksid" title="Natriumhydroksid">Natriumhydroksid</a> (NaOH)</li> <li><a href="/wiki/Natriumhydrogenkarbonat" class="mw-redirect" title="Natriumhydrogenkarbonat">Natriumhydrogenkarbonat</a> eller <a href="/wiki/Natriumbikarbonat" class="mw-redirect" title="Natriumbikarbonat">natriumbikarbonat</a> (NaHCO<sub>3</sub>)</li> <li><a href="/wiki/Natriumklorid" title="Natriumklorid">Natriumklorid</a> (NaCl)</li> <li><a href="/w/index.php?title=Natriumnitrat&action=edit&redlink=1" class="new" title="Natriumnitrat (sida finst ikkje)">Natriumnitrat</a> (NaNO<sub>3</sub>)</li></ul> <div class="mw-heading mw-heading2"><h2 id="Bruk">Bruk</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Natrium&veaction=edit&section=4" title="Endre bolk: Bruk" class="mw-editsection-visualeditor"><span>endre</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Natrium&action=edit&section=4" title="Rediger kildekoden til seksjonen Bruk"><span>endre wikiteksten</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Natrium er det alkalimetallet som er viktigast industrielt.
