Given:
To find:
Temporary and permanent hardness of water
Explanation:
- Temporary hardness is due to the carbonate salts while permanent hardness is due to the non-carbonate salts.
- In this case ; temporary hardness will be given by :
Sum of hardness due to carbonates :
Calcium and magnesium carbonates :
To calculate the hardness in french degrees (°Fr) :
1°Fr
°Fr ( Temporary hardness )
- Permanent hardness of water is given by :
sum of hardness due to non carbonates:
°Fr (permanent hardness)
