Let `(+)` tartaric acid has a specific rotation of`+11.1`, Calculate the specific rotation of a mixture of `68%(+)` tartaric acid and `32%(-)` tartaric acid.

Meso-tartaric acid and d-tartaric acid are

Meso-tartaric acid and d-tartaric acid are

d-tartaric acid and l-tartaric acid are:

Mesotartaric acid and d-tartaric acid are

d-tartaric acid and l-tartric acid are

(+) Mandelic acid has a specific rotation of +158^@ . What would be the observed rotation of a mixture of 30% (-) mandelic acid and 70% (+) mandelic acid

(+) mandelic acid has a specific rotation of 158^(@) What would be the observed specific rotation of a mixture of 25% (-) mandelic acid and 75% (+) mandelic acid ?

Dextro - tartaric acid and meso - tartaric acid are :
