What telescope do I need to split HIP 109831?

Splitting HIP 109831 requires an aperture of roughly 420 mm or larger — the components are separated by about 1.4″ at magnitudes near 5.7. The companion is about 4.4 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
