Why is it all right to use a wet flask for titration?

Truong-Son N. Because the mols of acid don’t change with the amount of solvent present. Since the mols are independent of what volume of solvent you have (the mols being of the SOLUTE), adding more water makes no difference as to what number of mols of acid you involve in the titration.

Can a beaker be used in titration?

A specific volume of the solution under test is collected and put into a container which is usually an erlenmeyer flask or a beaker. The container can be glass, plastic or another material. The size of the beaker or flask should be chosen to allow for more liquid to be added during the titration process.

How do you ensure all solutions in a pipette is transferred into a conical flask?

Prior to this, the pipette should have been rinsed with distilled water, followed by the solution it is to be filled with, again to avoid contamination. Once the solution is in the pipette, it’s then transferred to a conical flask.

What does adding NaOH to a solution do?

Neutralization. A base like sodium hydroxide can react with an acid to neutralize it. In this type of reaction, the hydroxide ion will accept a proton from the acid to form a molecule of water (H2O). Adding sodium hydroxide to a solution of an acid can neutralize some of the acid in the water.

How would it affect your results if you used a wet Erlenmeyer flask?

How would it affect your results if you used a wet Erlenmeyer flask instead of a dry one when transferring your acid solution from the volumetric pipette? – With a wet Erlenmeyer flask, the result will not be accurate. It might be contaminated by any type of liquid such as basic or acidic.

Does the addition of water affect the result of the titration?

It does not affect the titration reading as water does not react with the reagents or change the number of moles of acid added.

Why must you use a dry beaker?

The reason for this is based on the experiment being conducted. The reason could be to keep measured amounts exact (drops of water on the beaker adds to the volume of the substance within the beaker) or to keep impurities out of the contents of the beaker.

Why must the beaker and filter funnel be rinsed with distilled water?

Rinsing after creating the solution: to make sure all of the solvent is transferred to the volumetric flask. To ensure no loss of dissolved solute ; rinsing ensures all dissolved solute in the residual solution in the beaker and the flask enters into the standard volumetric flask .

Why is rinsing important in titration?

The titration is an analytical method, which allows to estimate the concentration of the given solution. Thus, you have to rinse the burette with a solution which must be filled in it, because distilled water change the concentration of the initial solution.

What does NaOH produce when it is placed in a water solution quizlet?

What does NaOH produce when it is placed in a water solution? Since it is a base, NaOH forms hydroxide ions, OH− ions, when placed in water solution. H3O+ ions are produced by acids. Basic solutions have a greater concentration of hydroxide ions, OH−, than hydronium ions, H3O+.

What does hydroxide react with?

Sodium hydroxide reacts with strong acids (hydrochloric, sulfuric or nitric), water, and moisture to rapidly release heat. Sodium hydroxide reacts with metals (aluminum, lead, tin or zinc) to form flammable and explosive hydrogen gas.

Does a wet Erlenmeyer flask causes errors in titration?

How would it affect your results if you used a wet Erlenmeyer flask instead of a dry one when transferring your acid solution from the volumetric pipette? – With a wet Erlenmeyer flask, the result will not be accurate. Therefore, an error will occur since it is not 100\% acid.
