Every character on Jiǎoluò Shūwū read as bai in any tone — 2 readings total across the four tones. Pick the tone you mean.
If you have the sound bai but not the character, here are the 2 characters read this way: 白 (bái, white, clear, plain, in vain), 百 (bǎi, hundred; all kinds of). They split across 2 tones, so the tone is what separates them.
