使用Potassium oxalate is a white crystal or powder made by neutralizing oxalic acid with potassium carbonate. It is soluble in water 1:3 but not in alcohol. Potassium oxalate was used as an early developer for gelatin plates but is best known as the developer for platinum prints.
一般的な説明Potassium oxalate, K2C204, H20, is odorless, efforescent, water-soluble, colorless crystals that decompose when heated. Sinks in and mixes slowly with water. Used in analytical chemistry and photography, and as a bleach and oxalic acid source.
