Question

A beaker contains NaOH and 5 drops of Universal Indicator.To this beaker Sulphuric Acid was added until no more changes.Describe how the indicator colour changes as the reaction proceeds with respect to the change in the ph of the solution

Answer 1

when universal indicator is added to NaOH colour changes to dark blue ph is 14 but when H2SO4 is added acid nullifies base thus making solution neutral. ... thus ph turns 7 with no effect on adding universal indicator. .. ☺☺

Answer 2

when universal indicator is added to NaOH colour changes to dark blue ph is 13 but when H2SO4 is added acid nullifies base thus making solution neutral the H+ ions react with OH- ions to form water. thus ph turns 7 with which no effect on adding universal indicatoris seen.
