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.
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 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.
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.
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.
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 does the volume of water in a titration not matter?
The volume of water in a titration does not matter because it does not participate in the chemical reaction taking place. The key factor in a titration is the concentration and volume of the analyte and titrant being used. The volume of water is often used to dilute the solutions to a manageable volume for titration.
When NaOH is diluted to half of its original concentration what affect does this have on titration?
If NaOH is diluted to half of its original concentration, this would mean that the molarity has also been halved. During titration, this would result in requiring twice the volume of the diluted NaOH solution to reach the endpoint compared to the original concentration.
Why Gycerol is used for the titration of NaOH with Borax?
Glycerol is often used as a solvent in the titration of NaOH with borax because it is a non-reactive substance that can dissolve both NaOH and borax. It helps to maintain a consistent medium for the titration, ensuring accurate results. Additionally, glycerol has a high boiling point which can prevent evaporation during the titration process.
