What metal element dissolved in nitric acid solution turns blood red with a Potassium thiocyanate test?
Iron (III) combines with the thiocyanate ion (SCN-) to make Iron Thiocyanate, which is a blood red compound.
The two solutions most commonly used to make Iron Thiocyanate are Iron (III) Chloride (clearish yellowish brownish solution) and Potassium Thiocyanate (clear solution).

What element is responsible for the purple color in KMnO4?
Manganese (Mn) is responsible for the purple color in KMnO4. When potassium permanganate is dissolved in water, it dissociates into potassium ions and manganese ions, giving the solution its distinct purple hue.
What happens when a solution of chlorine is mixed separately with potassium bromine solution and potassium iodide?
When chlorine is mixed with potassium bromide solution, chlorine will displace bromine to form potassium chloride. Similarly, when chlorine is mixed with potassium iodide solution, chlorine will displace iodine to form potassium chloride. These reactions are examples of displacement reactions where a more reactive element displaces a less reactive element from its compound.
What is the solute for antiseptic iodine?
The solute in antiseptic iodine is typically iodine itself, which is a chemical element. Iodine is dissolved in a solvent, such as alcohol or water, to create an antiseptic solution for disinfecting wounds and skin.
Is saline a compound or an element?
Saline is not a compound or an element; it is a solution of salt (sodium chloride) dissolved in water.
What element forms an alkali when added to water?
Potassium is an element that forms an alkali solution when added to water. It reacts vigorously with water to produce potassium hydroxide, which is a strong base.

Is gold a solution?
No, gold is not a solution. Gold is a pure element and not a mixture of substances dissolved in a solvent.
What is potassium and magnesium?
POTASSIUM: Potassium is a chemical element. It has the symbol K and atomic number 19. MAGNESIUM: Magnesium is a chemical element with the symbol Mg, the atomic number 12, and an atomic mass of 24.31. Magnesium is the ninth most abundant element in the Earth by mass. It constitutes about 2% of the Earth's crust by mass, and it is the third most abundant element dissolved in seawater.
Is potassium neutral or ion?
Potassiuim metal is neutral. Potassium in a solution of water forms an ion. Potassium in a compound with almost any other element forms an ionic bond.
Is potassium an element or compound?
Potassium is an element.
