On which thermometric property is the constant-volume gas thermometer based?
It is based on the pressure of a fixed mass of gas.
When the solution is diluted the volume will be more?
When a solution is diluted, additional solvent is added, which increases the total volume of the solution. This dilution process reduces the concentration of the solute in the solution while keeping the amount of solute constant.
How can you calculate the concentration of a phosphoric acid solution from the titration with sodium hydroxide?
You can calculate the concentration of a phosphoric acid solution by determining the volume of sodium hydroxide needed to neutralize it in a titration. The molarity of the sodium hydroxide solution and the balanced chemical equation for the reaction will allow you to find the moles of phosphoric acid present, hence the concentration.
Do the volume of the material stays constant when a solution is diluted?
No, the volume of the material increases when a solution is diluted because you are adding more solvent to decrease the concentration of the solute. Diluting a solution does not change the total amount of material present, but it does change the volume in which that material is dispersed.
What will happen to the molarity of NaOH If a drop of NaOH falls out of the flask during the titration?
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
How do you calculate concentration from a thermometric titration?
To calculate the concentration from a thermometric titration, you would plot a graph of temperature change against the volume of titrant added. The end point of the titration is indicated by the maximum or minimum point on the graph. By using the volume of titrant at the end point and the stoichiometry of the reaction, you can then calculate the concentration of the analyte.
On which thermometric property is the constant-volume gas thermometer based?
It is based on the pressure of a fixed mass of gas.
What is the control variable in a titration lab?
The control variable in a titration lab is the volume and concentration of the titrant solution being used. Keeping these variables constant ensures that any changes observed in the reaction are due to the titrated solution being analyzed, rather than variations in the titrant solution.
How do you calculate the moles of H2SO4 in a titration?
To calculate the moles of H2SO4 in a titration, you can use the formula: moles Molarity x Volume. First, determine the molarity of the H2SO4 solution. Then, measure the volume of the solution used in the titration. Multiply the molarity by the volume to find the moles of H2SO4.
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.
What is double titration?
Double titration is a titration method used to determine the concentration of a solution by performing two successive titrations. In the first titration, a known concentration of a standard solution is used to titrate the unknown solution. In the second titration, a different standard solution is titrated with the excess volume from the first titration to determine its concentration.
What apparatus is used in a titration experiment?
A burette is typically used in a titration experiment to deliver a measured volume of one solution (the titrant) into another solution (the analyte). The burette is filled with the titrant and the volume of titrant delivered is carefully monitored during the titration process.
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.
Why does adding distilled water in the conical flask during titration not affect the titration result?
Adding distilled water in the conical flask during titration does not affect the titration result because the volume of the solution in the conical flask affects the concentration of the titrant solution. As long as the same volume of titrant is delivered from the burette and reacts with the analyte, the concentration of the titrant and the volume of the analyte solution will remain the same, ensuring accurate results.
What is titration formula?
The formula for titration involves calculating the volume of titrant solution needed to reach the endpoint of a reaction with the analyte. It is typically given as M1V1 = M2V2, where M1 is the molarity of the titrant, V1 is the volume of titrant used, M2 is the molarity of the analyte, and V2 is the volume of analyte solution used.
What are the answers to the determination of iron by redox titration?
The answers to the determination of iron by redox titration are the concentration of the iron solution and the volume of the titrant needed to reach the endpoint of the titration.
What apparatus is used in titration?
A burette is typically used in titration to deliver a precise volume of a solution into another solution until the reaction reaches completion, as indicated by a color change or other observable change. The burette allows for the careful measurement of the volume of solution added during the titration process.
