Cesium carbonate ke motsoako oa inorganic. Ke bosoeu bo tiileng mocheso oa kamore le khatello. E qhibiliha haholo metsing 'me e monya mongobo kapele ha e behiloe moeeng. Tharollo ea metsi ea cesium carbonate e matla a alkaline 'me e ka itšoara ka asiti ho hlahisa letsoai le metsi a cesium, le ho lokolla carbon dioxide. Cesium carbonate e bonolo ho fetoha 'me e ka sebelisoa e le selelekela sa matsoai a mang a cesium. E sebelisoa haholo mefuteng ea letsoai la cesium.
