Hardness of Water | Class 11

In this module, you will:
⚫ learn about temporary and permanent hardness of water.
• Temporary hardness of the water is due to the presence of calcium and
magnesium bicarbonates.
• It can be removed by:
■ Boiling
■ Clark's method
• Permanent hardness of water is due to the presence of calcium and
magnesium chlorides and sulphates.
• It can be removed by:
■Treatment with washing soda
■ Calgon's method
AASOKA presents a video that talks about the temporary and permanent hardness of water and various methods for the removal of the hardness of the water.
AASOKA provides 2D/3D educational videos based on the CBSE curriculum that will help you understand difficult concepts and complicated experiments in a simple, easy-to-understand way.

"Hard water" is a difficult topic in chemistry programs. It becomes understandable through your presentation! You have taught science to the whole world. It's so admirable! I hope we can do the same in the future. Thanks a lot!

[@karistral.firdaus5770]

this is really useful! can u please do a video on EDTA used to determine the hardness of water ? thank u :)

[@ashutoshsuman9473]

At 1:40 and 1:53 you've said "resulting salt Calcium Carbonate and Magnesium Hydroxide". But isn't Magnesium Hydroxide is a Base. It should be replaced with Magnesium Carbonate. Other than that video was helpful for visualisation. Thanks

[@naseemyousuf529]

I thought the same...
The reaction should form MgCO3+CO2+H2O

[@ambarishbera4897]

Are yaar pahla mgco3 form hoga or badd me heat de raha ha to hydrolysis ka baja se H20 se react kar ke mg(oh) bananta hai

[@AASOKA_Learning]
