What is differnece in dl-malic acid and malic acid?
There are two different structures of malic acid, an L-isomer and a D-isomer. These two molecules are identical like your left and right hands. While they have the same atoms and bonds, they are not necessarily interchangeable, just as you cannot fit your left hand in a right hand-shaped hole. L-Malic acid is produced naturally in fruits. 90% of the acid in apples is malic acid. When malic acid is produced synthetically, a mixture of the two isomers is obtained which is called DL-malic acid (because it contains both D- and L-malic acid). When you eat DL-malic acid, your body digests the L-malic acid normally (it is part of the Kreb's cycle), but the D-malic acid is excreted in the urine. A 1967 study by the WHO shows evidence that D-malic acid is toxic and causes renal damage. When purchasing malic acid, if it is called "malic acid" it is likely DL-malic acid. If the natural form is desired, purchase specifically L-malic acid.

When limestone fizzes when acid is added is physical or chemical change?
The fizzing of limestone when acid is added is a chemical change. This is because a chemical reaction occurs between the acid and the calcium carbonate in the limestone, resulting in the production of carbon dioxide gas.
