How many moles of NaOH were used in the titration process?
The number of moles of NaOH used in the titration process can be calculated by dividing the volume of NaOH solution used by the molarity of the NaOH solution.
Why do you use ethanolic NaOH instead of aq NaOH in titration?
Ethanolic NaOH is used instead of aqueous NaOH in titration to avoid side reactions with water and reduce error in the titration process. The absence of water in ethanolic NaOH helps maintain the concentration and stability of the solution, resulting in more accurate and precise titration results.
Which indicator is used in titration of naoh and h2so4?
Phenolphthalein is commonly used as an indicator in the titration of NaOH and H2SO4. It changes color from colorless to pink as the solution reaches a specific pH range, signaling the endpoint of the titration.
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.
Why Gycerol is used for the titration of NaOH with Borax?
cuz' borax contain boric acid (H3BO3) which is very weak acid , thus it gives non accurate titration, so we add neutral glycerol to increase the acidity by the way we add glycerol after titration of NaOH not before

Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes, you can use indicators such as bromothymol blue or methyl orange in the titration of NaOH. These indicators change color at different pH ranges and can be used based on the specific pH endpoint needed for the titration.
Why is it necessary to standardize the NaOH solution before titration?
Standardizing the NaOH solution before titration is important to accurately determine its actual concentration. This ensures the accuracy and reliability of the titration results by eliminating any discrepancies that may arise from variations in the concentration of the NaOH solution.
What happened if some solution splashes out during the titration of NaOH?
If some solution splashes out during the titration of NaOH, it could result in a decrease in the volume of the solution being titrated. This can lead to an inaccurate reading of the amount of titrant used and affect the accuracy of the titration results. It is important to take precautions to prevent spills and maintain a consistent volume throughout the titration process.
If 20.0 mL of 150 M NaOH are used in a titration how many moles of NaOH are used?
To calculate the moles of NaOH used in the titration, multiply the volume (in liters) by the molarity. Converting 20.0 mL to liters (20.0 mL * 1 L/1000 mL = 0.020 L), the moles of NaOH used would be (0.020 L * 150 mol/L = 3.0 moles of NaOH).
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.
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 is the recommended concentration of NaOH for a successful titration experiment?
The recommended concentration of NaOH for a successful titration experiment is typically around 0.1 to 0.5 M (molarity).
