What is the positive result for mucic acid test?
When galactose is oxidized by nitric acid, insoluble mucic acid is formed. A positive result is the formation of a precipitate. Lactose is a dimer of glucose and galactose. The nitric acid will hydrolyze the dimer and so lactose will also give a positive result.

Why is the Benedict test not exclusive to glucose?
The Benedict test will return a positive value for any reducing sugar. It will work with fructose, for example. Benedict solution oxidizes all the reducing sugars such as glucose, galactose and fructose. This implies that a positive result of Benedict's test can be any of the reducing sugars, not necessarily glucose. It will oxidize the carbonyl (which present in all type of sugar classes). So if we get a positive result in the Benedict test, it is not necessarily glucose; it could be galactose or fructose that also a reducing sugar. So Benedict test can't be used to assure glucose.
