The correct answer is
E, D, C, B, A
Liming Materials CCE % Order Determination
The neutralizing value, expressed as Calcium Carbonate Equivalent (CCE %), indicates a liming material's capacity to neutralize soil acidity compared to pure calcium carbonate ($\text{CaCO}_3$). A higher CCE % signifies greater neutralizing power per unit weight.
The CCE % is calculated based on the chemical composition and molecular weights. Theoretical and typical CCE % values are:
| Material | Chemical Formula / Type | Approx. CCE % |
|---|---|---|
| A. Calcium oxide | $\text{CaO}$ | 178.5% |
| B. Calcium hydroxide | $\text{Ca(OH)}_2$ | 135.0% |
| C. Dolomite | $\text{CaCO}_3 \cdot \text{MgCO}_3$ | ~108.6% (Theoretical for pure) |
| D. Calcite | $\text{CaCO}_3$ | 100.0% (Baseline) |
| E. Basic Slag | Variable byproduct | ~50% (Typical value) |
Arranging Materials by Increasing Neutralizing Value
To determine the increasing order of CCE %, compare the values:
- Basic Slag (E) has the lowest typical CCE % (~50%).
- Calcite (D), pure $\text{CaCO}_3$, is the standard with 100% CCE.
- Dolomite (C) ($\text{CaCO}_3 \cdot \text{MgCO}_3$) has a theoretical CCE slightly above Calcite (~108.6%).
- Calcium hydroxide (B) has a higher CCE (~135.0%).
- Calcium oxide (A) has the highest CCE (~178.5%).
The order of materials from lowest to highest CCE % is: E < D < C < B < A
This corresponds to: Basic Slag < Calcite < Dolomite < Calcium hydroxide < Calcium oxide.
