What be the noticable difference between adding 20 drops then 20 more of first 1 molar KOH, then in a separate trial 1 Molar NaOH into a saturated NaCl soln which its self is about 20 drops(1ml)?

when KOH is added to NaCl no change takes place as KOH and NaCl issolve in solution but on addition of NaOH common ion effect takes place on Na+ ions and NaCl gets precipitated
