    Not very acidic, still a weak acid - mixed with a strong base.

    If it's a strong base, it will accept protons.

    So, the OH groups will deprotonate?

    Producing salt.

    Note - no idea what is the second pKa, so it is better to not be so sure both groups will be deprotonated.

    Oh, so you think just one group would deprotonate?

    Depends on pH.
