Question 28 (3 points) A student performs a titration procedure by adding NaOH to a solution that contains H+ ions. She added the indicator, phenolphthalein, to the flask containing the H+ ions. What was the purpose of adding the indicator to the flask? The indicator adds more Htions to the solution which allows the titration procedure to proceed O faster The indicator is expected to turn pink when the end point of the neutralization reaction occurs. The indicator was used to determine when the amount of Ht ions was greater than the O concentration of OH- ions. Go to Submit Quiz Solution 28. Addition of NaOH to a solution haivng H+ ions. Indicator is added to, -The indicator is expected to turn pink when the end point of the neutralization reaction occurs -- 26. compound that could serve as a reactant in a neutralization reaction is, H2SO4 -- 25. A solution has [H+] = 1 x 10^-9 M pH of the solution = -log(1 x 10^-9) = 9 Answer. 9.0 .
