I was wondering is it normal to have white tongue..?

White tongue?: All white? No. Slight white coating only on top, maybe. You need to be personally examined. Some white coatings are common and benign while others may reflect oral thrush, leukoplakia, lichen planus, or some other serious conditions. See a local oral surgeon for a diagnosis (and possible biopsy).

White tongue: Normal no. Consistent with oral hygiene maybe. Yes you wish to be rid of this. Try baking soda TP ...Armond Hammer has this. Sweep your tongue with a Soft brush with warm water. twice daily to clear the tongue. Use a chlorohexidene mouth wash 2XD. Be Hydrated .Drink 2 Litters of h2O dailey.
