To determine alkalinity of given water sample

[@sharktank2003]

Please provide the formula and calculation will help the needy one as per your observation table

[@dr.monikasujitchavan8039]

Total alkalinity= ml of total acid used* normality of acid * 50 * 1000/ml of water sample used

[@ArpanNaskar-wi5jf]

​@@dr.monikasujitchavan8039 Viva question: in this formula,why we are multiplying by 50?

[@jeevanpatidar-c2g]

Sup so easy for understand.

[@swatipatil7376]

Mam, determination of sulphate by spectrophotometer , please video

[@GHANSHYAMSINGH-cu1wk]

Thank you ma'am 👌👌👌

[@stylishpankajyadav]

Nice!

[@babasahebgaikwad7837]

0.02 sulphuric acid kase banavayache madam

[@Mirah165]

Ma’am what will be the formula for the overall total alkalinity….Means you have suggested to make separate table so the values will also come separately….Then what about total alkalinity

[@dr.monikasujitchavan8039]

You can do summation of methyl orang alkalinity and phenolphthalein alkalinity. Or Formula Total alkalinity =(A*B) * N of acid* 50 * 1000/ ml of water used. When A & B (Burette reading) is ml of acid used for methyl orange alkalinity and phenolphthalein alkalinity resp.

[@doddasreddy20873]

Madam, water sample means, normal water or mixture of sodium carbonate and sodium bi carbonate or pl tell me the concentrations of entire solutions and water sample, thank you

[@dr.monikasujitchavan8039]

Yes. Its a mixture of carbonate and bicarbonate.

I got a water sample with 7.2 pH. Then after an addition of POP the solution remained colorless, is there a need to continue with MO?

[@vishalmangaraj]

Same here ✋

[@Vegito9000]

mam can you tell me why we multiply it by 50

[@dr.monikasujitchavan8039]

Because here we are calculating acidity, alkalinity (quality parameters) in equivalent to CaCO3. So multiply with 50(equivalent wt. Of CaCO3.)

[@wazir252]

Lab safety protocols should be followed. You are sucking the sample through mouth.

[@dineshs921]

Ma'am I have textile waste water which is black in color so the color change is not forming. Should I mix it with distilled water to get results?

[@dr.monikasujitchavan8039]

But Colour won't be change by adding water.

[@asadali5895]

If acid is already present in sample will phenolphthalein will change the color of sample

[@dr.monikasujitchavan8039]

Sample remains colourless when Phenolphthalein is added in acidic water sample

[@asadali5895]

Thanks 👍🏽

[@hackstricks13]

What acid mam u use in Burette

[@dr.monikasujitchavan8039]

0.01 HCl is used.

[@nakkadurgaprasad7]

0.02N H2SO4 in burette also used in my lab .is it correct procedure mam?

[@VaishnaviSiddhewar]

Mam how to do calculation

Mam ur teaching is very good mam only the voice is problem but other then everything is nice and😢 one kind thing is pls put & tell wear gloves in laboratories. Don’t mistake me iam also environment lab chemist that’s y I told to u mam

How to determine acidity for food sample

[@satishprasadyadav]

Thank you so much mam.

[@anoop6929]

❤❤

[@agriinfinity5869]

Mam plz provide acidity formula

[@dr.monikasujitchavan8039]

Acidity=ml of NaOH * Normality of NaOH * 50 * 1000/ml of water titrated

[@nurayesrayazc8077]

Thank you. However, how possibly a doctor do not use hand gloves and lab coat while handling acid, be careful.

[@ramaswamy1438]

What is 50 and 1000 is this factor ?

[@dr.monikasujitchavan8039]

Here alkalinity is determine equivalent to CaCO3 therefore 50 (equivalent wt = 50) . Also it is calculated per liter so 1000

Madam everything is good but you need glp

Voice is very low, I can't hear it

[@Star_ff135]

Mam ,0.16 u asked how water become acidic? and answered how water become Alkaline.😅

[@dr.monikasujitchavan8039]

Water become acidic due to acidic gases, acidic salt, acidic industrial waste. Alkaline industrial waste, alkaline salt present in water causes alkalinity to water.

[@dr.monikasujitchavan8039]

It's 1.6 ml

Ok mam. 0. 16 is time stamp mam
