I believe that the original white powder isolated from lemon juice is an acid. Some characteristics of an acid is being described here like tasting sour, conducts electricity when in water and having a pH less than 7. Also, turning the litmus paper into red indicates that it is an acid. Hope this answers the question. Have a nice day.
