Determination or Assay of Sodium Chloride (NaCl) by Titration_A Complete Procedure (Mohr’s Method)

[@simplifiedchemistry3459]

❤ Very Nice 👍

[@MK-wo6rf]

In the last calculation, may I ask where did 0.00584/0.1 came from? Is this related to the molar mass of NaCL? Thank you!

[@Hakimmobariz-wu6jm]

Hello brother, I encountered this problem. I follow the video method. It turns white but does not turn orange. Please help me find a solution. I would be grateful. I do not know what the problem is with the sodium chlorite test

[@patricialancho806]

very well explained, thanks

[@drnerminelmasry2134]

actual normality for silver nitrate should be (0.101) not 0.099 because (N*v) for Sodium chloride =(N*v) for silver nitrates (0.1*10)=(9.9*N) silver nitrite so normality silver nitrite =0.101 in case of sample preparation you weight 0.25 and dissolved in 50 ml of distilled water if i use 25 ml can affect on the result or no

[@MicroChemsExperiments]

Drnermin Elmasry, Thank you for your observations. You are right about the Actual Normality. You can also use 25ml distilled water instead of 50ml and it will not cause any error in the result.

[@kaleemshaikh6793]

at 7:29 you add 25 ml of water again in conical flask... It means you dissolve 0.25 gram of Nacl in 50 ml of water... Now the are question is - are u preparing it 0.1 N concentration or it is necessary to take 0.25 gram of Nacl in 50 ml of water.

[@MicroChemsExperiments]

It is necessary to dissolve 0.25g in 50ml

[@huynhthixuanthuy2322]

Why you used 0,00584 and 0,1 in calculation ?

[@MicroChemsExperiments]

0.00584 is a calculation factor. 0.1 is the normality of AgNO3.

Can we use potassium chromate used as indicator

[@MicroChemsExperiments]

No

No Sorry potassium di-chromate

[@maisarah9296]

Can i know which reagent have to freshly prepared? Or can be prepared and stored for further analysis?

[@MicroChemsExperiments]

Potassium Chromate and AgNO3 should be prepared freshly. Others can be stored for future analysis

[@Hakimmobariz-wu6jm]

Hello, I am following the entire video procedure. When I add one milliliter of potassium chromate, it turns yellow and I titrate it with silver nitrite. No yellow color turns to red-orange. Please reply. It is urgent.

[@tic857]

I'm testing tap water, why isnt my solution turning a milky color like yours? Is it because it has a low concentration Chloride from NaCl? Or does it react differently when the Cl source is calcium hypochlorite?

[@MicroChemsExperiments]

NaCl concentration in tap water is very low (may be less than 100ppm). This low concentration of NaCl can not be determined by this method. Maximum chlorine in tap water may be present in other forms rather than NaCl.
