differentiate between permanent and Temporary hardness (5 points)
Answers
Answer:
Temporary Hardness Permanent Hardness
Temporary hardness is caused by the presence of dissolved bicarbonates of calcium, magnesium, and other heavy metals and the bicarbonates of iron.,The salts responsible for temporary hardness are Ca(HCO3)2 , Mg(HCO3)2 It is due to presence of dissolved chlorides and sulphates of calcium, magnesium, iron and other heavy metals.
Temporary hardness can be largely removed by boiling when bicarbonates are decomposed yielding insoluble carbonates on hydroids. Permanent hardness cannot be removed by boiling.
Temporary hardness is called as carbonate or alkaline hardness It is also known as non-carbonate or non-alkaline hardness
