Which indicator is used for titration of C2H2O4 with NaOH?
Phenolphtalein change colorless at pH < 8 to purple blue at pH > 8 to 10
What happens if you mix bromphenol blue and NaOH?
When bromophenol blue is mixed with NaOH, the solution turns blue because the pH becomes alkaline. Bromophenol blue is a pH indicator that changes color in different pH ranges. In the presence of NaOH, which is a base, the bromophenol blue changes from yellow (at acidic pH) to blue (at alkaline pH).
What are different types of indicator used in titration?
Common indicators used in titrations include phenolphthalein (colorless to pink at a pH around 8-10), methyl orange (red at pH <3.1, yellow at pH >4.4), bromothymol blue (yellow at pH <6, blue at pH >7.6), and litmus (red at pH <4.5, blue at pH >8.3). Each indicator changes color at a specific pH range, allowing for the determination of the endpoint of the titration.
Which indicator is used for 8-6 pH?
Bromothymol blue (pH 6.0-7.6) Phenol red (pH 6.4-8.0) Neutral red (pH 6.8-8.0)
