It turns blue in the presence of Fe2+, and can be used to check for possible oxidation/rust
The chemical formula of lithium ferricyanide is L3[Fe(CN6].
329.244 g/mol
The reaction between potassium nitrate and potassium ferricyanide does not involve a direct single displacement or double displacement reaction. Hence, no specific products can be predicted for this combination.
Turnbull's blue is ferrous ferricyanide, Fe3[Fe(CN)6]2
Fish and amphibians are two groups of animals that typically fertilize externally. They release their eggs and sperm into the water to fertilize externally rather than internally.
Potassium ferricyanide cannot be used as an internal indicator because it is an external indicator that does not change color in response to pH changes in a solution. Internal indicators are usually weak organic acids or bases that change color due to ionization changes as the pH of the solution shifts.
The official IUPAC name is potassium hexacyanoferrate. The formula is:K3[Fe(CN6)]
Charges: Potassium = +1 Ferricyanide = -3
The chemical formula of lithium ferricyanide is L3[Fe(CN6].
4. K3, 1 Ferricyanide.
This chemical formula of the ferricyanide anion is [Fe(CN)6]3.
-1
K3Fe(CN)6, also known as potassium ferricyanide, is often used as an external indicator in redox titrations because of its distinct color change. It turns from yellow to colorless upon reaction with excess titrant, making it easy to visually detect the endpoint of the titration.
The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.

The reaction between potassium nitrate and potassium ferricyanide does not involve a direct single displacement or double displacement reaction. Hence, no specific products can be predicted for this combination.
An external indicator in titration is a substance that is added in small amounts to the analyte solution during titration to signal the endpoint of the reaction. It changes color at or near the equivalence point, making it easier for the observer to detect when the reaction is complete. Common examples of external indicators include phenolphthalein and methyl orange.
