What are the expected products of hydrolysis of lactose?

Explanation

Lactose (a disaccharide), on hydrolysis yields a `1 : 1` mixture of the monosaccharides -D -(+) -glucose and `D-(+)-` galactose.
`underset("Lactose")(C_(12)H_(22)O_(11)) + H_(2)O underset("or Lactase")overset(H_(3)O^(+))rarr underset(D-(+)-"glucose")(C_(6)H_(12)O_(6)) + underset(D-(+)-"galactose")(C_(6) H_(12)O_(6))`
