Why Would Blue Litmus Paper Turn White Instead Of Stay The Same Color Or Turn Red When Mixing Base/acid?

That's the acid.. If you use water onto the blue litmus paper, you'll realize that the color will stay the same cause the water's pH value is almost 7 which means it neutral. Besides, the blur litmus paper isn't just a simple paper, it also contains some kind of chemicals. And if you use something alkaline onto the red litmus paper, it'll turn blue. I hope you understood and that my answer helps =)

The Blue litmus paper should not change color in water normally.
But if you dip it in water taken freshly from a tap, it can have Chlorine mixed with it which can bleach the litmus paper and hence it can turn white.
