Question

Can i tirate a solution of unknown concentration with other solution of unknown concentration and still get a meaningful answer

Answer 1

NO.  You can do such a titration to an end-point, but it will be meaningless because you don't have 2 unknowns, i.e. the concentration of the both solutions.  So, at the end of the titration, you will not be able to conduct any meaningful calculations.
