Homework Help: chemistry (buffers)

How can weak acid nitrous acid HNO2 form a buffer solution with equal concentrations and volumes with weak base NH3?

I thought that buffer solutions only occured between weak acids and strong bases or vice versa. The example above as two weak soltuions.

Buffers are combinations of a weak acid and a weak base, not a weak acid and a strong base.
