Editing Potassium (section)

===Food additives===
Potassium sodium tartrate ({{chem2|KNaC4H4O6}}, [[Rochelle salt]]) is a main constituent of some varieties of [[baking powder]]; it is also used in the [[silvering]] of mirrors. [[Potassium bromate]] ({{chem2|KBrO3}}) is a strong oxidizer (E924), used to improve [[dough]] strength and rise height. [[Potassium bisulfite]] ({{chem2|KHSO3}}) is used as a food preservative, for example in [[wine]] and [[beer]]-making (but not in meats). It is also used to [[bleach]] textiles and straw, and in the tanning of [[leather]]s.<ref>{{cite book|chapter-url = https://books.google.com/books?id=XqKF7PqV02cC&pg=PA86|page = 86|chapter = Bleaching and Maturing Agents|title = How Baking Works: Exploring the Fundamentals of Baking Science|isbn = 978-0-470-39267-6|author = Figoni, Paula I|date= 2010|publisher=John Wiley and Sons}}</ref><ref>{{cite book|chapter-url = https://books.google.com/books?id=eblAtwEXffcC&pg=PA4|publisher=Academic Press|pages = 4–6| chapter = Uses and Exposure to Sulfites in Food|title = Advances in food research|isbn = 978-0-12-016430-1|author = Chichester, C.
