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.
How much grams of ferric chloride to be added in 100ml of water to get 2 percent solution?
To prepare a 2% solution of ferric chloride in 100ml of water, you would need to add 2 grams of ferric chloride. This is calculated by multiplying the volume of the solution (100ml) by the desired concentration (2%) and converting it to grams.
How can you prepare ferrous oxalate?
Add ferrous chloride solid to saturated aqueous solution of oxalic acid then to expel the HCl gas then saturated solution is allow to cool the crystals of ferrous oxalate settled down with in few minutes remove the excess liquid and get the dry compound.
What is a simple test for presence of tannic acid?
Tannic acid is a type of polyphenol with the chemical formula of C76H52O46. A simple test for tannic acid is to add the substance to distilled water. Then add two drops of ferric chloride. If this results in a greenish precipitate, it indicates the presence of tannic acid.
Why would you add sulfuric acid to a mixture of oxalic acid and sodium oxalate?
This is an example of a buffer solution. if the sulfuric acid were added to a plain glass of water, it would have a massive change in pH. However, the buffer action of the oxalate-oxalic acid solution will decrease this change to something very minor (demonstrably to only hundredths or thousands, if the solution is made well, of the change it would have on pure water).

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 water would I add to a 50percent solution of H2O2 to make 500 ml of 3percent H2O2?
To make a 500 ml solution of 3% H2O2 from a 50% solution, you would need to dilute the 50% solution with water. You would add 325 ml of water to 175 ml of the 50% H2O2 solution to achieve a final volume of 500 ml with a concentration of 3% H2O2.
What happens if you add another atom of oxygen to a molecule of water?
H2O2 is the hydrogen peroxide.

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 formula for iron ion III?
Fe+3 Cl-1

What is the equivalent weight of sodium oxalate?
mw : 134 /2= 67
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.
