The neutralising values of the following liming materials are such that
A. CaO > Ca(OH)2 > CaCO3 > CaMg(CO3)2
B. CaO > Ca(OH)2 > CaMg(CO3)2 > CaCO3
C. Ca(OH)2 > CaO > CaMg(CO3)2 > CaCO3Oa
D. CaCO3 > CaO > Ca(OH)2 > CaMg(CO3)2
Answer: Option B
Solution (By Examveda Team)
The neutralizing value is the percentage of the material that can neutralize acid expressed as the calcium carbonate equivalence (CCE) of the product.The neutralizing values of the following liming materials are such that:
CaO > Ca(OH)2 > CaMg(CO3)2 > CaCO3
Calcium oxide has the highest value i.e. 178.5, followed by 135 of calcium hydroxide, then 108.5 of calcium magnesium carbonate and lastly 100 of calcium carbonate.
