Which indicator is suitable for the titration of HCl and NaOH?
A suitable indicator for the titration of the weak acid CH3COOH(aq) and the strong base NaOH(aq) would be either thymol blue (pH range 8.0 – 9.6) or phenolphthalein (pH range 8.3 – 10.0).
What indicator will be used in the HCl and NaOH titration experiment provided in lab technique #3?
Phenolphthalein
In each of two trials, a 0.500 M NaOH(aq) solution is added to a flask containing a volume of HCl(aq) solution of unknown concentration. Phenolphthalein is the indicator used in the titration.
Which indicator may be used during titration of HCl?
phenolphthalein indicator
A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions.
What indicator is suitable for titration?
Phenolphthalein, a commonly used indicator in acid and base titration.
What indicators are used in titration?
Acid–base titration
| Indicator | Color on acidic side | Range of color change (pH) |
|---|---|---|
| Methyl red | Red | 4.4–6.3 |
| Litmus | Red | 5.0–8.0 |
| Bromothymol blue | Yellow | 6.0–7.6 |
| Phenolphthalein | Colorless | 8.3–10.0 |
Which of the following indicator S can be used in the titration of VS Naoh is are?
Phenolphthalein is the best indicator for the detection of equivalence point in the titration of a weak acid (such as oxalic acid) and a strong base (such as sodium hydroxide).
Which indicator is suitable for the titration between HCl and NH4OH?
The methyl orange is best suited for the purpose. Thus, option (D) is the correct option.
Which of the following indicator S can be used in the titration of VS NaOH is are?
What is a suitable indicator for titration of Naoh and oxalic acid?
Hence, the indicator used for the titration of oxalic acid with sodium hydroxide is phenolphthalein.
Why are two indicators used in titration?
In the titration of polyacidic base or polybasic acid there are more than one end point. One indicator is not able to give color change at every end point. So to find out each end point we have to use more than one indicator. It is because all indicator changes color on the basis of pH of medium.
Which indicator is used in titration of oxalic acid with Naoh?
phenolphthalein
Hence, the indicator used for the titration of oxalic acid with sodium hydroxide is phenolphthalein.
