Sprite Zero - Soda or Not?

Is Sprite Zero considered soda?

I mean, there is no color, sugar, caffiene or carbs. Is it just flavored water that is carbonated?

Here are the ingredients:

carbonated water, citric acid, natural flavors, potassium citrate, and potassium benzoate, aspartame, acesulfame potassium.

The last two are artificial flavors/sweeteners - this classifies it as a soda in my book.

It’s a pop.

Right, I was going to say pop, but living in texas (Im from Ohio) I get strange looks when I say pop for soda
