The platinum electrode, also known as the working electrode, is where the oxidation-reduction reactions occur. It either serves as an electron donor or an electron acceptor. A voltage is generated which is compared to the reference electrode (Ag\/AgCl). An ORP sensor is typically used to measure the oxidizing or reducing potential of a water sample.<\/p>\n<p>Cyclic Voltammetry uses a three-electrode system. A potential is applied to the working electrode where the redox reaction takes place. The second functional electrode is the reference electrode. This electrode serves as a reference standard against which the potentials of the other electrodes present in the cell can be measured. The third electrode is the counter or auxiliary electrode which serves as a source or sink for electrons so that current can be passed from the external circuit through the cell.<\/p>","protected":false},"excerpt":{"rendered":"<p>No. None of our ORP sensors can be used for Cyclic Voltammetry; but\u00a0 we do offer an instrument that will do this directly: The Oxidation-Reduction&#8230;<\/p>\n","protected":false},"author":11015,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[],"tags":[57,3949,1897,6589],"class_list":["post-3917","post","type-post","status-publish","format-standard","hentry","tag-cv","tag-electrochemistry","tag-orp-bta","tag-potentiometry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/3917","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/users\/11015"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/comments?post=3917"}],"version-history":[{"count":0,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/3917\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/media?parent=3917"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/categories?post=3917"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/tags?post=3917"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
