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 value of ferric chloride?
The ferric chloride solution is acidic.
What are chemical properties of ferric carbonate?
This compound doesn't exist.
What is the pH of FeNO33?
The pH of ferric nitrate solution is acidic.
Oppositely charged ions in solution are prevented from combining by?
Oppositely charged ions in solution are prevented from combining primarily due to the presence of solvent molecules, which solvate the ions and create a stable environment that reduces their effective attraction. Additionally, the thermal motion of the solvent molecules keeps the ions dispersed and prevents them from coming together to form solid compounds. This dynamic balance allows ions to exist in solution without precipitating out.
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.
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.
Making of ferric alum?
Ferric alum is made by dissolving bauxite in sulfuric acid to obtain aluminum sulfate. Ferric oxide is then added to this solution to form ferric alum. The solution is then set aside for the crystals of ferric alum to form through a process called crystallization.
