What is the chemical test to distinguish between sodium sulphate and ammonium sulphate ferric salt and ferrous salt?
To distinguish between sodium sulfate and ammonium sulfate, you can add barium chloride (BaCl₂) solution to the samples. Sodium sulfate will not produce any precipitate, while ammonium sulfate will give a white precipitate of barium sulfate (BaSO₄). For differentiating ferric salt from ferrous salt, adding potassium thiocyanate (KSCN) to a ferric salt solution will produce a blood-red complex (ferric thiocyanate), while ferrous salt will not produce this color change.
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 formula mass of ferric sulphate Fe2SO43?
The molar mass of Fe2(SO4)3 is 399,88 g (anhydrous).
What happens when freshly prepared solution of ferrous sulphate followed by conc.H2SO4 is added to nitric acid?
You can obtain the ferric sulphate - Fe2(SO4)3; because the ferrous sulphate react as a reducing agent.
What would happen if ferrous ammonium sulfate or ferric ammonium citrate in KIA is omitted?
If ferrous ammonium sulfate or ferric ammonium citrate is omitted from Kligler's Iron Agar (KIA), the medium would lack the essential iron source needed for the detection of hydrogen sulfide (H2S) production. This would prevent the formation of a black precipitate, which indicates H2S production by bacteria. Additionally, the absence of these iron compounds could affect the overall pH indicators, potentially leading to inaccurate results in sugar fermentation tests. Overall, the omission would compromise the ability to identify certain bacteria effectively.
What is the equivalent weight of ferric ammonium sulphate?
The equivalent weight of ferric ammonium sulfate is 392.14 g/mol.
How do you dissolve ferric ammonium sulphate in water?
To dissolve ferric ammonium sulfate in water, add the powder gradually to water while stirring continuously. Make sure to make a concentrated solution by adding the powder in small amounts and stirring until fully dissolved. Heating the water slightly can also help in dissolving the compound faster.

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 is the chemical abbreviation for Ferric Ammonium Oxalate?
The chemical abbreviation for Ferric Ammonium Oxalate is FeNH4C2O4.
How do you make Ammonium ferric citrate?
Ammonium ferric citrate can be made by reacting ferric citrate with ammonium hydroxide. First, dissolve ferric citrate in water and then add a solution of ammonia until the desired pH is reached, followed by evaporation to get the final product.
How much elemental iron in 100 mg ferric ammonium citrate?
Ferric ammonium citrate contains about 20% elemental iron. So, in 100 mg of ferric ammonium citrate, there would be approximately 20 mg of elemental iron.
Lab preparation of neutral ferric chloride solution from solid ferric chloride?
To prepare a neutral ferric chloride solution from solid ferric chloride, first dissolve the solid ferric chloride in distilled water to form a concentrated solution. Then, slowly add a base such as sodium hydroxide solution while monitoring the pH using a pH meter until the desired neutral pH is reached. Finally, dilute the solution to the desired concentration with more distilled water if needed.
Is ferric ammonium sulfate a metal?
No, it contains metals in its formula, but is not a metal itself.
What is the colour of ferric sulphate solution?
Ferric sulphate solution is typically yellow in color, often ranging from pale yellow to dark amber depending on its concentration.
What is ferrice sulphate molecular formula?
Ferric sulphate, or iron (III) sulphate has the formula Fe2(SO4)3.
