How do you make 10 chromic acid?
Chromic acid is a commonly used glassware cleaning reagent. It is prepared in a one liter container by dissolving 60 grams of potassium dichromate in approximately 150 mls of warm distilled water and then slowly adding concentrated sulfuric acid to produce a total volume of one liter Chromic Acid solution.
What is chromic solution?
Chromic acid (H2 Cr O4) is a strong acid because hydrogen ions completely disassociate in the solution. To make chromic acid, sodium dichromate or potassium dichromate is mixed with a little water to make a paste. Adding sulfuric acid to the paste while stirring makes chromic acid.
What is the molecular weight of NaOH?
39.997 g/mol
Sodium hydroxide/Molar mass
What is the anion for chromic acid?
ion chromate
The ”chromic” in chromic acid comes from the polyatomic ion chromate. A polyatomic ion is a molecule with an electric charge. Chromate has a charge of negative two with the formula CrO4 -2.
How do you make 100ml of chromic acid?
To make chromic acid, sodium dichromate or potassium dichromate is mixed with a little water to make a paste. Adding sulfuric acid to the paste while stirring makes chromic acid.
What is the formula for chromic acid H2CrO4?
Chromic Acid is a naturally occurring oxide with a formula H 2 CrO 4. Chromic Acid is also called Tetraoxochromic acid or Chromic (VI) acid. It is usually a mixture made by adding concentrated sulphuric acid (H 2 SO 4) to a dichromate which consists of a variety of compounds and solid chromium trioxide.

How is chromic acid made in a dichromate?
It is usually a mixture made by adding concentrated sulphuric acid (H 2 SO 4) to a dichromate which consists of a variety of compounds and solid chromium trioxide. Molecular chromic acid – H 2 CrO 4 is similar to sulphuric acid (H 2 SO 4) as both are strong acids, however, only the first proton is lost easily.
How is H 2 CrO 4 similar to sulphuric acid?
Molecular chromic acid – H 2 CrO 4 is similar to sulphuric acid (H 2 SO 4) as both are strong acids, however, only the first proton is lost easily. Dichromic acid – H 2 Cr 2 O 7 is the fully protonated form of the dichromate (Cr 2 O 7–) ion.
