What else can I help you with?
Is Ferrous and Ferric diatomic and triatomic?
No. Ferrous and ferric cations are divalent and trivalent respectively, but both are only single atom ions.
What is the pH for ferric ammonium citrate?
Ferric ammonium citrate typically has a pH range of around 3.0 to 6.0 when dissolved in water, depending on its concentration and the specific formulation. This acidity is due to the presence of ferric ions and ammonium ions, which can release protons in solution. The exact pH may vary based on the specific product and its preparation method.
What is the pH value of ferric chloride?
The ferric chloride solution is acidic.
Why Fe 3 ions do not exist in solution?
Fe³⁺ ions do exist in solution, but they are not as stable as Fe²⁺ ions under typical conditions. In aqueous solutions, Fe³⁺ can rapidly hydrolyze to form hydroxocomplexes or precipitate as iron(III) hydroxide (Fe(OH)₃) when the pH is elevated. Additionally, the presence of ligands can further stabilize Fe³⁺ in solution, often leading to the formation of more soluble complexes. Thus, while Fe³⁺ ions are present in solution, their stability is influenced by the surrounding conditions.
What are chemical properties of ferric carbonate?
This compound doesn't exist.
What is the color of ferric chloride salt in water?
Ferric chloride gives green solution in waterReddish or yellowish
Is Ferrous and Ferric diatomic and triatomic?
No. Ferrous and ferric cations are divalent and trivalent respectively, but both are only single atom ions.
How does ferric chloride reacts with potassium iodide solution?
When ferric chloride (FeCl3) is added to a solution of potassium iodide (KI), it reacts to form iron(III) iodide (FeI3) and potassium chloride (KCl). The iron(III) iodide produced is a brownish-red color, indicating the presence of the Fe3+ ion. This reaction can be represented by the following chemical equation: 2FeCl3 + 6KI -> 2FeI3 + 6KCl
What would you observe when blue litmus is introduced into a solution of ferric chloride?
Blue litmus paper turning red indicates that the solution of ferric chloride is acidic. This is because ferric chloride is a strong acid, which will donate protons to the water molecules, increasing the concentration of H+ ions in the solution and lowering the pH.
What is the valency of ferric?
The valency of ferric is +3. This means that ferric ions have a positive charge of 3.
How do you a prepare ferric alum indicator?
To prepare ferric alum indicator, dissolve 5-10 grams of ferric ammonium sulfate in 100 ml of distilled water. This solution will serve as the indicator for chloride ions, turning yellow in the presence of chloride ions.
What colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution?
A red-brown colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution. This is due to the oxidation of ferrous ions in the solution to ferric ions, which results in the formation of ferric oxide/hydroxide on the surface of the zinc granules.
What is the pH for ferric ammonium citrate?
Ferric ammonium citrate typically has a pH range of around 3.0 to 6.0 when dissolved in water, depending on its concentration and the specific formulation. This acidity is due to the presence of ferric ions and ammonium ions, which can release protons in solution. The exact pH may vary based on the specific product and its preparation method.
Why should only freshly prepared solution of ferrous sulphate solution be used?
Freshly prepared solution of ferrous sulfate should be used because it is prone to oxidation when exposed to air, leading to the formation of ferric ions. This can result in inaccurate test results due to the presence of ferric ions instead of ferrous ions. Additionally, solutions that have been stored for extended periods of time may also be contaminated with impurities, affecting their effectiveness.
Do HCl and ferric nitrate form a precipitate?
Yes, a reaction between hydrochloric acid (HCl) and ferric nitrate (Fe(NO3)3) will result in the formation of a precipitate of iron(III) hydroxide (Fe(OH)3). This is because the chloride ions from HCl will displace the nitrate ions from ferric nitrate, leading to the formation of an insoluble iron(III) hydroxide precipitate.
What is the pH value of ferric chloride?
The ferric chloride solution is acidic.
What happen to the ferric oxide sol when sodium chloride is added?
The color of the fe2o3 became light when sodium chloride was added. Adding an electrolyte solution introduces oppositely charged ions that neutralize the surface charges of the particles which allow the particles to coagulate and settle.
