Which indicator is used in titration of oxalic acid with HCl?
Both HCl and oxalic acid are acids. Therefore, since there is no alkali present, these compounds do not undergo neutralization. So there is no suitable indicators for the addition of these two reagents.
Is phenolphthalein the indicator used in the titration of Na2CO3 against HCl solution?
Type your answer here... Phenolphthaelin indicator changes its colour at 8.3 pH. But the end point of this reaction is at pH 7. In weak base Strong acid case the curve gives sharp change from 3.2 to 6.0 pH. Hence phenolphthalein indicator will not be advicable.
Is methylorange the indicator used in the titration of Na2CO3 against HCl solution?
Methyl orange is not commonly used as an indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is a suitable indicator for this titration because it changes color in the pH range of the equivalence point.
Is methyl orange the indicator used in the titration of na2co3 against hcl solution?
No, methyl orange is not commonly used as the indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is the indicator of choice for this titration, as the endpoint is at a pH of around 8.2, which is the color change range of phenolphthalein.
What can be added to HCl to turn red?
Adding phenolphthalein indicator to hydrochloric acid (HCl) will turn it red in basic solutions.

Which is best indicator for HCl plus Na2CO3?
methyl orange
How is an indicator used to determine the pH of a solution?
Iodine solution is an efficient indicator for starch. It will go from a light brown colour to a black colour if starch is present and will stay light brown if no starch is present. Hope this Helps!
Why we used methyl red as indicator in titration borax with HCL?
Methyl red is used as an indicator in the titration of borax with HCl because it changes color in acidic conditions. This allows for the precise determination of the endpoint of the titration, which is when all of the borax has reacted with the acid. The color change indicates the shift from basic to acidic conditions, helping to stop the titration at the correct point.
NH3 is titrated with HCl which indicator is suitable?
Methyl orange is a suitable indicator for the titration of NH3 with HCl because the pH range for the color change of methyl orange (pH 3.1-4.4) corresponds well with the equivalence point of the reaction between NH3 and HCl (pH 4.74).
In HCl and NaOH titration which indicator is used?
Phenolphthalein is commonly used as an indicator in the titration of hydrochloric acid (HCl) with sodium hydroxide (NaOH). Phenolphthalein changes color from colorless to pink at the endpoint of the titration when all the acid has been neutralized by the base.
Why is Volume of HCl used for blank titration is more than volume of HCl used for oil titration?
The blank titration is used to determine the exact amount of acid needed to neutralize any impurities in the titration setup, such as the indicator and solvent. This additional volume of acid is accounted for in the blank titration and is subtracted from the volume of acid used in the titration with the oil sample.
Why bromocresol indicator used for sodium carbonate and HCl titration?
Bromocresol green is used as an indicator in the titration of sodium carbonate with hydrochloric acid because it changes color within the pH range of the endpoint of the titration. It turns yellow in acidic solutions (due to excess HCl) and blue in basic solutions (due to excess Na2CO3), making it suitable for detecting the equivalence point where the moles of acid have reacted completely with the moles of base.
