otassium Chromate botnfellur with and coumpnd that contains a cation and NO 3 , also known as the polyatomic ion Nitrate. Three common examples of this are Zinc Nitrate (Zn(NO 3 ) 2 ) Silver Nitrate (AgNO 3 ) and Baruim Nitrate (Ba(NO 3 ) 2 ) The common-ion effect is a hugtak used to describe the effect on a solution of two dissolved solutes that contain the same ion. The presence of a common ion bælir niður the ionization of a weak acid or a weak base . [ edit ] Examples Ef bæði NaCH 3 COO and CH 3 COOH eru leystar upp í sömu lausn skiljast þau bæði að og jónast og framleiða salt jónir. NaCH 3 COO er sterk sýra svo að hún skilst fullkomlega að í lausn. CH 3 COOH er veik sýra svo að hún jónast ekki fullkomlega. Samkvæmt lögmáli Le Chatelier, þá hægir insetning salt jónanna úr NaCH 3 COO á jónun CH 3 COOH og breytir jafnvæginu til vinstri. Sem sagt klofnunin á CH 3 COOH minnkar og pH lausnarinnar eykst, hún verður basískari. NaC
