| A hydrochlorate, a sulphate, an aurochloride, and a platinic chloride of betaine have been prepared. |
| These are distinguished from solutions of the platinic salts by not being precipitated by chloride of ammonium. |
| After heating, the melted mass will have an alkaline reaction, and give a precipitate with platinic chloride. |
| As platinic metals have a high tendency to form complexes, the complex-forming sorbents are particularly useful. |
| By heating to below redness the platinic chloride and digesting with hydrate of potassium the residue. |
| They are soluble in water and give characteristic precipitates with platinic and auric chlorides, and with potassium ferrocyanide. |
