Phenolphthalein is normally used for this reaction as it accurately displays the end point of the reaction, turning colorless as soon as it reaches the end point of the reaction. If carrying out this reaction, be careful, as the change is usually quite sudden. The color exhibited should be pink (or "fuchsia") at the beginning of the reaction. As it progresses, it should become lighter in color, until it becomes colorless suddenly.
What else can I help you with?
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.
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 is the equation of sodium hydroxide with phenolphthalein with hydrochloric acid?
The equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) using phenolphthalein indicator is: NaOH + HCl → NaCl + H2O Phenolphthalein is a pH indicator that turns pink in basic solutions and colorless in acidic solutions.
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.
What indicator or indicators are used for HCl versus KOH?
For the titration of hydrochloric acid (HCl) versus potassium hydroxide (KOH), phenolphthalein is commonly used as an indicator. Phenolphthalein changes color from colorless to pink at pH 8.2-10.0, which corresponds to the endpoint of the titration when all the HCl has reacted with KOH.

How you determine the concentration of hcl of new bottle?
To determine the concentration of hydrochloric acid (HCl) in a new bottle, you can perform a titration using a standard solution of a strong base, such as sodium hydroxide (NaOH). First, you would dilute a known volume of HCl and then gradually add the NaOH solution until you reach the endpoint, indicated by a color change from a pH indicator like phenolphthalein. By applying the titration formula (M1V1 = M2V2), you can calculate the concentration of the HCl based on the volume and concentration of the NaOH used. Additionally, you could use techniques like pH measurement or conductometric titration for more precise results.
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.
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.
Why methyl orange is used instead of phenolphthalein in hcl and naoh titration?
This is so since the pH at the end point of Phenolphthalein is 9.1 and methyl orange is 3.7. For a strong acid strong base titration which the end point is between 3-11 phenolphthalein is used
What is nature of titration curve obtained in titration of hcl against naoh?
The titration curve obtained in titration of HCl against NaOH is a typical acid-base titration curve. It shows a gradual increase in pH at the beginning due to the addition of base (NaOH). At the equivalence point, the curve shows a sharp increase in pH since all the HCl has been neutralized. After the equivalence point, the pH continues to rise as excess NaOH is added.
What volume of NaOH was used in the titration?
To determine the volume of NaOH used in the titration, you need to know the concentration of the NaOH solution and the volume required to reach the endpoint. Use the formula: volume NaOH (L) = volume HCl (L) * concentration HCl / concentration NaOH.
What can be added to HCl to turn red?
Adding phenolphthalein indicator to hydrochloric acid (HCl) will turn it red in basic solutions.
