If the concentration of fluoride anion and aluminum cation was increased to 5 m, then the measured ecell would have a charge of 0.0550.
Fluoride (/ ˈflʊəraɪd, ˈflɔːr- /) [3] is an inorganic monatomic anion of fluorine of the chemical formula F-(also referred to as [F] -), the salt of which is usually white or colorless. Fluoride salts usually have a noticeable bitter taste and are odorless.
Its salts and minerals are important chemical reagents and industrial chemicals and are mainly used to produce hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base because it binds only partially in solution, but concentrated fluoride is corrosive and can attack the skin.
Fluoride is the simplest fluoride anion. Fluoride ions are similar in charge and size to hydroxide ions. Fluoride ions are found in some minerals on Earth, especially fluorite, but are naturally found in trace amounts in the aquatic environment.
