hi during a science lab we tesed various unknown substances to classify them as either acid or base.

Some of the indicators that were used was:
bromthymol blue,
blue/red litmus paper,
phenophthalein .

One of the substances was acid according to 2 indicators but it was base according to the other two. Is this substance acid or base?
