How much of NaOH were used in the titration?
The amount of NaOH used in a titration depends on the volume and concentration of the NaOH solution used in the experiment. To calculate the exact amount of NaOH used, you would need to know the molarity of the NaOH solution and the volume used in the titration.
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.
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.
How do you achieve accurate volume of NaOH during titration?
To achieve accurate volume of NaOH during titration, you should use a calibrated burette to deliver the NaOH solution, ensure the meniscus of the liquid is at eye level when taking readings, and record the volume added precisely at the endpoint of the titration when the indicator changes color. Practice consistent technique and avoid parallax errors for accurate volume measurements.
How is the titration of H3PO4 with NaOH performed to determine the equivalence point?
During the titration of H3PO4 with NaOH to determine the equivalence point, a known volume of H3PO4 is gradually added to a solution of NaOH until the reaction reaches a neutral point. This is detected using an indicator that changes color at the equivalence point. The volume of NaOH required to reach this point is used to calculate the concentration of H3PO4.

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.
What is the concentration of the base (NaOH) in the following titration?
To determine the concentration of the base (NaOH) in a titration, you would use the volume of the base added and the volume and concentration of the acid (typically HCl). By using the balanced chemical equation and the volume and concentration of the acid, you can calculate the concentration of the base.
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.
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).
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.
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.
Which is the best method of estimate acetic acid in pharmaceutical and commercial preparation?
The best method for estimating acetic acid in pharmaceutical and commercial preparations is typically titration using a standardized sodium hydroxide (NaOH) solution. This method involves titrating a known volume of acetic acid solution with NaOH until a color change occurs, indicating neutralization. The volume of NaOH used can then be used to calculate the concentration of acetic acid in the sample.
