It's 2-methylpropan-1-ol oxidized with potassium dichromate(VI) in aqueous sulphuric acid to yield 2-methylpropanoic acid (also known as isobutyric acid).
It is commonly made in the laboratory by reacting a lead(II) salt (such as lead(II) nitrate) with a chromate or dichromate salt (such as potassium chromate or potassium dichromate) in solution in water, producing a very deep yellow to orange precipitate of lead(II) chromate.ead(II) chromate is used in some pyrotechnic compositions, especially delay compositions, as an oxidizer. Up to the late 1800s it was used to impart a bright yellow color to some types of candy. It has also been used in the paint to color school buses.(Chrome Yellow). Previously, its use was wider.
