Preparation & Standardization of 0.1N Sodium Hydroxide (NaOH) Solution_Chemical Preparation (Part-2)

Chemical and reagent preparation is very crucial for any test. We must prepare chemicals and reagents to get the accurate test results. This video represents a complete procedure for the preparation and standardization of 0.1N sodium hydroxide solution. __________________________________________________________________________________________

Sir what ml of HCL we should take for 1N NAOH, and how many drops of phnolpthaleine indicator

[@kunika3282]

Incredulous explanation 🙌🙌

[@MicroChemsExperiments]

Glad you think so!

[@mehulprajapati7105]

Is there possible to final reading is hier then initial reading???? Because if supposed we start a titration from 20 ml and add NaoH in the flask of Hcl then how can the reading is then the initial reading Reading is below to the 20 ml for final reading... Plz explain it

[@SohelRana-ln7bg]

Pls share how to calculate the purity of reagent. That's means Assay of NaOH is 98% Purity = 40* 100/98 is ot correct?

How to take the initial reading...please help me

[@user-ii4ed5ch4t]

purpose of experment?

[@sonunegi4356]

I am. Not understand at the time of titration u have taken 20ml NaOh intiial but at final how it is goes 30.2ml ?? On titration it would reduce reading because drops going out in flask??? Please answer

[@MicroChemsExperiments]

The titration reading, at the initial stage, was 20ml. After completion of the titration, the reading was 30.2. Burette scalling was that type that is increased the reading with time. So you need to subtract to find the actual volume which was 10.2 found in this video.

Hello is it the same procedure for preparation and standardization of 0.1N KOH?

[@MicroChemsExperiments]

Yes. Procedure is similar, except weight of KOH pellet.

[@abdhjr4780]

[@padmaboddupalli6369]

Explain the initial value 20,NaoH is titrate through which chemical for standardization

[@MicroChemsExperiments]

Initial value was 20 because the burette reading was 20.0 when the titration just started. Take a look at the video - 3.42 min

[@mailtonousad]

[@MicroChemsExperiments]

[@rania5349]

Well explained, thank you so much. I'm wondering about the reference if you can give it to me

[@MicroChemsExperiments]

No exact reference for this video. This is derived from the acid base neutralisation chemical reaction.

[@msanthosh4980]

Is this standardization procedure applicable for all chemicals..?

[@MicroChemsExperiments]

No. Only for NaOH

[@kaushaldewangan6500]

Sir... 0.098 Normality ke NaoH solution ko 0.1 Normality karna hai to kitna gram NaoH dalna padega ... calculation karke bataye.....ya kisi aur ko pata ho to bataiye .. please

[@MicroChemsExperiments]

I think it is difficult to calculate.

[@bibabenouamane334]

Please can you explain to me why you use 2g of phenol on 100 ethanol i found just 1g

[@MicroChemsExperiments]

It is just a indicator dye. Concentration can vary

You can standardize NaOH solution using potassium hydrogen phthalate and you can also use standard HCl solution

[@MicroChemsExperiments]

Look at 3.44 time of this video. You could see the solution in the burette touches the label of 20. That's why the initial burette reading is 20.

Acid Base titration

Hcl is also a secondary std solution. How did you standardise naoh with hcl?🤨

I don’t also get it but I think she means performing titration with HCl ( known concentration) to ascertain or confirm the concentration of NaOH Prepared.

How about alkali standardization with potassium hydrogen pethelet?

[@rolandleka5342]

Volumetric pipette of 10 ml should be used ad it is more accurate. Hcl is somewhat volatile and tends to loose concentration even slightly. And finally, before performing standardization you must treat the NaOH with few drops of barium chloride in order to remove carbonates which are always present. Solution must then be filtered and standardized
