Determination of Alkalinity of Water_A Complete Procedure (AOAC 973.43 & IS 3025.23)

[@karthikpharmacist5271]

Your communication and way of teaching is awesome mam

[@MicroChemsExperiments]

Thank you Sir

For mixed Indicator, I think the right weight is 0.2g Methyl Red and 0.1g Bromocresol green Not 0.02g Methyl Red and 0.01g Bromocresol green.

[@kingrobert2063]

when i added phenolpthalin indicator in tap water of my lab then there was no colour change ...it means i have to titrate only for methyl orange indicator??

[@MicroChemsExperiments]

Yes

[@rajeshmala1490]

Thank for video. Where to get 0.02 N sulphuric acid. Any manufacturers

[@MicroChemsExperiments]

We have prepared a video for the preparation of 0.02N sulphuric acid. Video link: kzbin.info/www/bejne/aX6on3utqb2ap6M Follow this video

[@pranabkumardas8575]

Thanks for this type of videos. Please make a video on Limit test of Lead according to USP

[@MicroChemsExperiments]

Already uploaded. 1. Watch sample preparation by Wet Digestion Method for Lead analysis and prepare your sample accordingly. 2. Then analyze the prepare sample using AAS as described in Sodium Analysis of Salt.

[@NaveenNaveen-gu2re]

We r using N/50 sulfuric acid it can be any change in the test results

[@Samuraijack113]

I have a doubt in calculation, what is 5000?

[@nurliyanaazman2743]

If I dilute the sample, is the calculation still the same?

[@MicroChemsExperiments]

Dilution factor will be multiplied with the test result

[@kizitoarinze7903]

Hello, please explain more about the calculation factor (50000) is it a constant?

[@MicroChemsExperiments]

We will explain it later

[@baldevsinghmehta1911]

Yes!! plz explain calculation factor? 50000?

[@mohamedrafi6908]

Phenlopthalein alkalinity and bicarbonate alkalinity both are same?

[@MicroChemsExperiments]

No

[@mohamedrafi6908]

@@MicroChemsExperiments let me know what is phenlopthalein alkalinity

[@user-je1fg2xk5e]

Thanks again 😬 finally i am done with my assignment because of your videos. 💕💕💕

[@MicroChemsExperiments]

Thank you

[@InBtGP]

Hey mam, What solution used for increasing pH level

[@MicroChemsExperiments]

Sodium hydroxide solution

[@chandramohannukala233]

Madam. In calculation part 50000 means

[@MicroChemsExperiments]

Calculation factor

[@chem_cafe7781]

is the water sample we taken is normal tap water?

[@MicroChemsExperiments]

No. It was a treated waste water sample.

[@salinyaiyer]

Thank you

[@MicroChemsExperiments]

You are welcome

[@wellwisher066]

why we can't only do total alkalinity? what's the difference

[@MicroChemsExperiments]

If you want to find the total alkalinity you have to do sum of phenolphthalein alkalinity and mixed indicator alkalinity. Because two indicators work in different ph range and the whole ph range is the total alkalinity which can't be determined by only a singe indicator.

@@MicroChemsExperiments thanks or answer, thumbs up

[@MicroChemsExperiments]

@@wellwisher066 You are most welcome.

[@prasannaudayakumara2319]

Can we use hcl 0.02N solution for this test and it's calculations difference

[@MicroChemsExperiments]

Prasanna Udaya Kumara, IS reference method said to use H2SO4. So you should use sulfuric acid.

[@b95-z1f]

What if the pH is below 8.3?

[@MicroChemsExperiments]

The result will not be accurate

[@aymenogkush]

Please can you make a video for TVBN in Fish? Keep up the good work !

[@MicroChemsExperiments]

Aymenogkush, thank you for your comment. We will work on TVBN test soon. Stay with us.
