Measurement And Units of Hardness By Dr. Nisha Singh

This video is about measurement of hardness in terms of calcium carbonate equivalent. It also covers the units of hardness and their inter relation.

Mam At 7:10
Equivalent weight of mgcl2 might be
10*50/47.5 = 10.5263 mg/litre
Is this correct??
Btw awesome explanation...

[@dr.nishasingh]

Yes it should be 47.5
I have written 55.5 by mistake.
Thanks for mentioning

Maam mgcl2 equivalent weight is 47.5

[@dr.nishasingh]

Yes

[@livecodealone]

Yes

[@THENOOB-s1i]

Thnx a lot mam for this lecture ❤❤

Most welcome 🙂

[@thejatadda598]

Mam mgcl2 ka 59.5 hota h 55.5 bss suggestions tha mam mera or koi mean nhi tha

[@dr.nishasingh]

should be 47.5

[@Saiyanism031]

Mam but in the book, its mentioned that the formula of (equivalent of CaCO3) is = (Amount of hardness producing salt x Molecular weight of CaCO3)/ Molecular weight of hardness producing salt .
And not equivalent weight

[@Saiyanism031]

Instead of using molecular weight you are telling us to use equivalent weight

[@dr.nishasingh]

Yes because molecule weight is not applicable for all salts and ions.

[@fashionkhan3155]

such a good teaching method maa'm

[@dr.nishasingh]

Thank you so much

[@Apparent302]

Is eq. wt. of MgCl2 is correct?

[@dr.nishasingh]

So sorry! It should be 47.5.
55.5 is the equivalent weight of CaCl2.

[@STEPSFORGATE]

Yes mam

[@jitendrakumar-sv9ku]

Nice explanation mam

[@dr.nishasingh]

Thanks dear
