What is the chemical composition of residue of ferric chloride and sodium hydroxide?
The residue from the reaction between ferric chloride and sodium hydroxide would likely contain iron hydroxide as a major component, with sodium chloride also present because of the initial reactants. The specific composition would depend on the stoichiometry of the reaction and any other impurities present in the starting materials.
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.
Explain how you would find the solubility of a solute?
To find the solubility of a solute, you would typically dissolve a known amount of the solute in a solvent at a specific temperature. Then you would measure the concentration of the solute in the resulting solution. The solubility of the solute at that temperature is the maximum amount that can dissolve in the solvent under those conditions.
Which of these would you expect to be true regarding the solubility of KOH in water?
KOH (potassium hydroxide) is a strong base and is highly soluble in water due to the strong electrostatic interactions between the potassium and hydroxide ions with water molecules. Therefore, you would expect KOH to dissolve readily in water to form a clear solution with high conductivity.
What test would you use to confirm that you have a solution of FeCl3?
You can use a precipitation test by adding NaOH solution to identify FeCl3, which forms a red-brown precipitate of iron hydroxide. Another test involves adding potassium ferrocyanide, which forms a deep blue precipitate of ferric ferrocyanide. Both of these confirm the presence of FeCl3.

What would be a good indicator of the solubility of a substance in a solute?
A good indicator of solubility is the maximum amount of solute that can dissolve in a solvent under specific conditions, often expressed as grams of solute per 100 ml of solvent at a certain temperature. Additionally, the solubility curve of a substance, showing how its solubility changes with temperature, can provide insight into its solubility characteristics.
What is the measure of how well a solute can dissolve at a given temperature?
The measure of how well a solute can dissolve at a given temperature is known as solubility. It is typically expressed as the maximum amount of solute that can dissolve in a specific amount of solvent under particular conditions, usually in grams of solute per 100 grams of solvent.

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.
What is another word for iron oxide?
ferrum (ferric, ferrous)

What would happen when blue litmus is put in ferric chloride solution?
Blue litmus paper would turn red in ferric chloride solution due to the acidic nature of the solution, which would cause a change in the pH of the litmus paper turning it to red.
What is the reaction between bismuth nitrate and ferric nitrate?
The reaction between bismuth nitrate and ferric nitrate would likely result in a double displacement reaction forming bismuth ferric nitrate. The specific chemical equation would be: Bi(NO3)3 + Fe(NO3)3 -> BiFe(NO3)6.
If you use potassium hydroxide instead of sodium hydroxide what salt would you make?
If you use potassium hydroxide instead of sodium hydroxide, you would make potassium salts instead of sodium salts. For example, if you reacted potassium hydroxide with hydrochloric acid, you would produce potassium chloride.
