If we are talking about distinguishing between the two solutions then,

Carry out a Benedict's test on both solutions;

Results:

Lactose solution would give a brick-red/brown precipitate (positive test)

Sucrose solution would give negative test result while sucrose is a non-reducing sugar which does not react with Benedict's reagent.

Is lactose in lactic acid?

No. Lactic acid is a different molecule than lactose. Molecular Formulas: Lactic Acid- C3H6O3 Lactose- C12H22O11 In addition, lactose is a sugar molecular while, as you may guess, lactic acid is an acid.
