Determination of Hardness of Water_A Complete Procedure (ASTM D1126-17)

water hardness is the amount of dissolved calcium and magnesium in the water. Hard water is high in dissolved minerals, largely calcium and magnesium. This video represents a complete procedure for the determination of total hardness of a water sample.

[@mdsajibhossain747]

I have a question, can i use the same methods for analysis of waste water and drinking water hardness.

[@MicroChemsExperiments]

You can

[@rianaaja144]

i have apprenticeship in some famous company,they do 100 ml sample not 50 ml,why is it?
and what is that 1000 in calculation? for mg?

[@bestallislamicvideo]

Not blue is violet colour

[@vinithakrishnan14]

How was the initial value of burette can be 33.9? I think the initial value of burette be zero is always🤔 can u explain?

[@MicroChemsExperiments]

If you set the initial value at 33.9, then it is possible. You just need to count the initial titrant volume

What's the Min. & Max. Limit of Hardnesses of water?

[@MicroChemsExperiments]

Varies with the type of sample.

[@WaleedKhan-cx7gl]

I have a question. How much gram of ebt is used when we have not available of ebt in solution

[@Sara-nj7ox]

I don't know why people put background music in educational videos

[@gamingbuddy979]

its total hardness of calcium or magnesium?

[@user-bn2hr1fe2s]

total hardness of mg or ca?

[@miketyson411]

In this procedure, the concentration of Eriochrome Black T was Unknown, doesn't the intensity of the indicator affects the end point determination??????

[@MicroChemsExperiments]

You are correct. Doesn't affect the endpoint

[@BasheerPallam-ob4ub]

Concentration must be 1%weight/volume.
Under normal condition Erichrome is not stable.

[@amiramohamed5316]

I did that but it took long time and didn't give the color , what the mistake did i do ?
Pleas help me

[@smaismaeil6262]

please help me how can i prepare EDTA...... thanks

[@MicroChemsExperiments]

We will make video soon

[@saravananKS26]

Water sample is normal water or what?

[@rudra9389]

Sir , I want
Determination of hydrogen sulphide of water A complete procedure.
Please make a video sir.

[@MicroChemsExperiments]

[@miketyson411]

just asking is it possible to use a normal buffer 10 instead of an ammonia buffer

[@MicroChemsExperiments]

In official method, it is said to use Ammonia Buffer 10. I think there will be no problem in using normal buffer instead of ammonia buffer but never tried. You can try this method by using both buffers in separate experiment to compare the results. If you found same result then continue using normal buffer 10.
Thank you

[@suyashharsh5100]

This is not complete procedure, Standardization you didn't do

[@MicroChemsExperiments]

You are correct. We will make another video for the standardization

[@MAhmad-px2xc]

1 my question when the calculat the hardness why 1000 multiply

[@user-lo8qj8wo1t]

Because we need to show the result in 1000ml i.e. in one litre(mg/litre)

[@shafiquebro2394]

41.3 - 33. How

[@shammahblessings5381]

how do i find magnesium from total hardness

[@MicroChemsExperiments]

Noted. We will make video later

[@shammahblessings5381]

how do i magnesium from total hardness

[@MicroChemsExperiments]

Noted. We will make video later

[@davidsinurat199]

sir I Want To ask V3x 1000 what is 1000? thanks

[@aichanidsaid4828]

1L litre

[@mehranyousaf3826]

Why we multiply with 1000....

[@MicroChemsExperiments]

This is the calculation factor

[@user-lo8qj8wo1t]

Because we need to show the result in 1000 ml i.e. one litre(mg/l)

[@mahedihasan-fq2oc]

I want ph and tds test

[@MicroChemsExperiments]

Ph test is already uploaded

[@saadraufrao8836]

How to find only calcium hardness?
