Mam can u explain this question
Q - 100 ml of water sample has hardness equivalent of 12.5 ml of 0.08N MgSO4 what is its hardness in ppm?

Put N1V1=N2V2 then S=NE

[@anuragchorghade1628]

Mam in the first numerical that you took....40.5 will be in mg ?...then equivalent weight would be in grams...so it would require conversion ??

[@chemistrybydr.anjalissaxena]

no conversion is required as you put value in mg

[@utkarshkumarsingh9898]

Mam mgco3 is permanent hardness not temporary hardness

[@sandeepchaurasiya3923]

Thanku mam..❤
But mam teperary and permanant ko kaise pahchan kre..

[@chemistrybydr.anjalissaxena]

Salts. See the first video lecture of same playlist

[@ansariaburehan263]

Ma'am you made a mistake in the last moment... When we want to convert it into degree french then we need to multiply the ppm by 10 and for degree clark multiply the ppm by 100/7... Also you can think like this that degree french is 1 part in 10^5 parts of water. So it should always be greater than PPM

[@chemistrybydr.anjalissaxena]

Ppm is 1 part in 10 ^6 part CaCO3
Degree French is 1 part In 10^5 part......
1ppm =1 mg/L =0.1 degree French

[@muskanagrawal1575]

Mam degree French mei convert krte time 10 se multiply krenge na
Aapne divide Kiya h
Mam pls reply
Kl exam h

[@chemistrybydr.anjalissaxena]

1Ppm= 1 mg/l= 0.1 degree french= .07 degree clark

[@yashsaxena878]

How we can know it is hardness or not hardness like NaHCo3

[@chemistrybydr.anjalissaxena]

Hardness is due to Ca or Mg salta only

[@rashmipriyqdarshnj6378]

Mgc03 produces permanant hardness ?

[@chemistrybydr.anjalissaxena]

No

[@aditiverma_h]

Ma'am can you explain with the examples in which normality and edta solution type questions included....please

[@chemistrybydr.anjalissaxena]

Ok

[@elf52_kalpitabelekar24]

how to identify that salt is temporary or permanant?

[@chemistrybydr.anjalissaxena]

On boiling the water if salt convert into that type of salt which does not produces hardness then it is temporary otherwise permanent.

[@rizwankhakra5475]

maam i think CO2 takes part in hardness...

[@chemistrybydr.anjalissaxena]

Carbonates

[@Darsh.r.m_20]

If it produces Ca++ and or Mg++ ions it will contribute

[@manojmeena6221]

Ma'am pls start a btch for competitive exams

mam mgco3 is permanent hard?
