What happens when oxalic acid reacts with sodium hydroxide?

Oxalic acid reacts with NaOH according to H2C2O2 + 2 NaOH –> Na2C2O2 + 2H2O. Calculate the mass of oxalic acid dihydrate (126.1 g/mol) required to react with 15.00 mL of 0.100 M NaOH.

What is the type of titration when oxalic acid is titrated with NaOH?

Here, the sodium hydroxide solution is not a primary standard and is taken in a burette and a known volume of the oxalic acid (a standard solution) is taken in the titration flask. In an acid-base titration, the amount of acid becomes chemically equivalent to the amount of base present in the end.

What is the aim of titrimetric analysis?

The purpose of titration is to determine an unknown concentration in a sample using an analytical method.

Why is standardizing NaOH important?

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 principle of acid base titration?

An acid–base titration is a method of quantitative analysis for determining the concentration of an acid or base by exactly neutralizing it with a standard solution of base or acid having known concentration. A pH indicator is used to monitor the progress of the acid–base reaction.

When oxalic acid is titrated with NaOH at the end point the solution becomes?

In acid base titration at the end point the amount of acid becomes chemically equivalent to the amount of base present. In case of strong acid and strong base titration at the end point of solution the solution become neutral.

What is the role of phenolphthalein for the standardization of NaOH solution by oxalic acid solution?

Sodium hydroxide reacts with oxalic acid in presence of phenolphthalein indicator. The color changes from colorless to pink at the end point. Hence, based on the above theory our aim is to prepare and standardize sodium hydroxide using oxalic acid.

Which indicator is suitable for h2so4 and na2co3?

Statement: Sodium carbonate can be titrated against sulphuric acid by using methyl orange as indicator. Explanation: The volume of sulphuric acid required to produce colour change for the two indicators (acid or basic) is different.
