# Can you standardize NaOH with HCl?

## Can you standardize NaOH with HCl?

Standardisation procedure One way of doing this (for a 0.1M NaOH solution) is to pipette 20.00 mL of standard 0.100 M HCl into a flask and adding a couple of drops of phenolphthalein indicator. Then fill your burette with the NaOH solution and titrate the HCl until the colour changes to a pale permanent pink.

How will you prepare 0.1 M HCl from 37% HCl?

Therefore add 8.3 ml of 37% HCL to 1 liter of D5W or NS to create a 0.1N HCL solution.

### How is standardization of NaOH done?

Standardization of sodium hydroxide is done by acid base titration. When oxalic acid is allowed to react with sodium hydroxide, sodium oxalate and water are obtained. In this titration, to locate the end point phenolphthalein indicator is used.

How can you prepare 1 Litre 1 N HCl solution?

If we add 8.33mL in 100 L of water we get 1 N HCl.

## What amount of HCl is present in 500ml of 0.1 N solution?

When 500 mL is divided by 1000 mL/L, we obtain a volume of 0.50 L. Now we have to convert the 3.0 mol of HCl into grams of HCl. This can be done by multiplying 3.0 mol by the molecular weight of HCl, which is 36.46 g/mol.

How do you test for normality of NaOH?

Once gram equivalent weight is understood, it is easier to understand the equation for normality:

1. Normality (N) = m /V × 1 / Eq.
2. Normality (N) = m /V × 1 / Eq.
3. m = 1 eq/L × 1 L × 40.00 g/eq ; therefore m = 40 g.

### Why sodium hydroxide is 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 purpose of standardization of NaOH?

STANDARDIZATION OF NaOH Purpose: You will precisely measure the concentration of the NaOH solution you prepared last lab by carrying out a series of acid/base neutralizations.

## What is the normality of 35% HCl?
