What was the indicator used when NaOH was taken in burette?

Use a pipette with pipette filler to transfer 25 (or 20) cm3 of 0.4 M sodium hydroxide solution to the conical flask, and add two drops of methyl orange indicator. Swirl gently to mix. Place the flask on a white tile or piece of clean white paper under the burette tap.

Which indicator is used in the titration of NaOH taken in burette vs HCL taken in titration flask and what is the color change at the endpoint?

In this case, hydrochloric acid is taken in the burette and sodium carbonate solution in the conical flask. Methyl orange is used as an indicator. The colour change at the end point will be from yellow to pinkish-red.

Which indicator would you use in the titration of sodium hydroxide against acetic acid?

phenolphthalein
A common acid-base indicator is phenolphthalein. Phenolphthalein is colorless in acidic solution, but changes to pink when the solution becomes basic. At the equivalence point, the moles of acetic acid are equal to the moles of sodium hydroxide, and the solution will turn pink as more sodium hydroxide is added.

How is titration performed?

The process is usually carried out by gradually adding a standard solution (i.e., a solution of known concentration) of titrating reagent, or titrant, from a burette, essentially a long, graduated measuring tube with a stopcock and a delivery tube at its lower end.

Why does the NaOH solution have to be standardized?

But when it comes to anything analytical where you start to involve calculations, standardization is a must. This is done with NaOH because it’s hygroscopic and readily sucks up the moisture in the air. So what is being weighed isn’t totally NaOH, but also the moisture that it has absorbed.

What is the chemical equation for the reaction between NaOH and acetic acid?

Note: Always remember that the balanced chemical equation between acetic acid and sodium hydroxide can be written as $NaOH + C{H_3}COOH \to C{H_3}COONa + {H_2}O$. It is called a neutralisation reaction. The reverse of neutralisation reaction is known as hydrolysis.

How does acetic acid react with NaOH?

In the reaction between acetic acid and sodium hydroxide, the acetic acid donates a proton to the hydroxide ion and acts as an acid. The hydroxide ion accepts a proton and acts as a base. The stoichiometric relationship between acetic acid and sodium hydroxide is 1:1 (from Equation 2).

How do you titrate a burette with oxalic acid?

Calculate it as a solution of oxalic acid M/10. Rinse the burette with the standard oxalic acid solution. Take 10cm 3 of oxalic acid solution in a titration flask. Fill the burette with sodium hydroxide solution. Remove the air gap if any, from the burette by running the solution forcefully from the burette nozzle and note the initial reading

What type of titration is used to detect acetic acid?

The most common type of titration is the acid-base titration. In this experiment, you will determine the concentration of acetic acid, HC2H3O2 in commercial vinegar. Vinegar is a mixture of acetic acid and water. In this titration, aqueous NaOH is the titrant, and vinegar is the analyte.

How to titrate NaOH solution with phenolphthalein indicator?

Pipette out 20ml of NaOH solution is a conical flask. Add 2-3 drops of phenolphthalein indicator to it. Titrate the base with oxalic acid solution until pink colour disappears. Repeat the titration till three concordant readings are obtained.

What is the titration for aqueous sodium hydroxide and vinegar?

Vinegar is a mixture of acetic acid and water. In this titration, aqueous NaOH is the titrant, and vinegar is the analyte. We assume that the strong base and the weak acid react completely according to the net equation:
