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 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.
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.
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.
Would CoCl2 6H2O cause a chemical reaction?
When CoCl2·6H2O is heated, the water molecules are driven off, leaving anhydrous CoCl2. This is a physical change, not a chemical reaction. However, the anhydrous CoCl2 can undergo chemical reactions depending on the conditions and other reactants present.

Why does a nail not go rusty if its in anhydrous calcium chloride?
The nail would not go rusty because it was kept dry and the anhydrous calcium chloride removed the moisture from the air
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 do you make anhydrous calcium chloride from calcium oxide?
To make anhydrous calcium chloride from calcium oxide, you would react calcium oxide with hydrochloric acid (HCl). This reaction will yield calcium chloride and water. The water produced in the reaction will need to be removed to obtain anhydrous calcium chloride.
What is the name of Fe2Cl3?
The chemical formula for ferrous chloride or iron (II) chloride is FeCl2.
Why would vanillin test positive in a ferric chloride test?
Vanillin contains aromatic groups that can form colored complexes with ferric chloride, resulting in a positive test by producing a color change. This reaction is commonly used to detect the presence of phenolic compounds like vanillin in a sample.
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.
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 is the colour of ferric chloride with salicylate?
The color of ferric chloride with salicylate is purple. This color change occurs when salicylate is added to a solution of ferric chloride, producing a complex between the two compounds that results in a purple color.
What reagents would you use for the synthesis of 1-chlorobutane from 1-butanol?
anhydrous Zinc chloride and aq.HCl or CaCl2 and HCl.
Can mars be change by another color?
if the composition of the air would change if the dust would be replaced from nanophase ferric oxides
