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.


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 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.


How would you know the Normality of HCL?

To determine the normality of HCl (hydrochloric acid), you can perform a titration experiment with a standardized solution of sodium hydroxide (NaOH) of known concentration. By recording the volume of NaOH required to neutralize the HCl, you can calculate the normality of the acid using the formula: Normality = (Molarity of NaOH) x (Volume of NaOH used) / Volume of HCl sample.

How can one standardize NaOH?

To standardize NaOH, one must titrate it against a known concentration of an acid, such as HCl, using an indicator to determine the endpoint of the reaction. The volume and concentration of the NaOH can then be calculated based on the volume of acid used in the titration. This process ensures that the concentration of the NaOH solution is accurately determined for future use in experiments.


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 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.


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.


What is the molarity of an hcl solution if 7ml hcl solution is titrated with 27.6ml of 0.170m of naoh solution?

The balanced chemical equation for the reaction is: HCl + NaOH -> NaCl + H2O. From the equation, it is a 1:1 mole ratio reaction. Therefore, the moles of HCl can be calculated from the volume and concentration of NaOH used in the titration. Then, use the moles of HCl and the volume of HCl solution used to calculate the molarity of the HCl solution.


Why methyl orange is used as an indicator in HCL and NaOH titration?

I don't know ... I have the same problem . I found this in a chemestry problem , and my teacher couldn't tell me the answer . He told me to search for it, but I can't find anything about the reaction between Methyl Orange and HCl .. If you could help me , please leave a message at YM : valentin_gr2008@yahoo.com Thanks !


A solution containing 3.76 g naoh in 361 ml water is titrated with 491 ml hcl what is the concentration of hcl in the original solution?

Given that the amount of NaOH is known, and the volume of HCl required for titration can be measured, you can calculate the concentration of HCl by using the balanced chemical equation and stoichiometry. The concentration of HCl in the original solution can be determined by dividing the moles of NaOH used in the reaction by the volume of HCl used. This calculation will yield the molarity of HCl in the original solution.
