Complexometric indicators are water-soluble organic molecules. Some examples are:

* [[Eriochrome Black T]] for [[calcium]], [[magnesium]] and [[aluminium]]

* [[Xylenol orange]] for [[gallium]], [[indium]] and [[scandium]]

* [[Methyl calcein blue]]

* [[Murexide]] calcium and [[rare earths]]

* [[Fast Sulphon Black]] with [[Ethylenediaminetetraacetic acid|EDTA]] for [[copper]]

* [[Eriochrome Red B]]

* [[Calcein]] with [[Ethylenediaminetetraacetic acid|EDTA]] for calcium

* [[Calcon]]

* [[Curcumin]] for [[boron]], although the red color change of curcumin also occurs for pH > 8.4

* [[Eriochrome blue-blackBlack BT]] for [[calcium]], [[magnesium]] and [[aluminium]]

* [[Fast Sulphon Black]] with [[Ethylenediaminetetraacetic acid|EDTA]] for [[copper]]

* [[Eriochrome blue SE]]

* [[Hydroxynaphthol blue]]

* [[Methylthymol blue]]

* [[Phthalein purple]]

* [[Pyrogallol red]]

* [[3,3'-dimethylnaphthidine]]

* [[Chromazurol S]]

* [[Hematoxylin]] for [[copper]]

* [[Murexide]] calcium and [[rare earths]]

* [[Naphthol green B]]

* [[EriochromeXylenol Black Torange]] for [[calciumgallium]], [[magnesiumindium]] and [[aluminiumscandium]]

* [[1-(2-pyridilazo)-2-naphthol]] (PAN)

* [[Calmagite]]

* [[2-Cresolphthalexon]]
