No change will occur on pouring solns from third and fourth testube on red and blue litmus paper

1. When the universal indicator is added to test tube 1 it turns RED in color as Hcl is a strong acid and when universal indicator is added to test tube 2 it becomes blue in color as NaOh is a strong base
