An aqueous solution of an unknown solute is tested with litmus
paper and found to be acidic. The solution is weakly conducting
compared with a solution of NaCl of the same concentration.

Which
of the following substances could the unknown be:
KOH,NH3,HNO3, KClO2, H3PO3, CH3COCH3 (acetone)?

I would go with H3PO3/
KOH, NH3, KClO2 solutions will be basic.
HNO3 is a strong electrolyte.
acetone doesn't ionize in water. That leaves just one.
