The Al and Si alloy shows only partial solubility. At 20 °C, the solubility of Si (solute) in Al (solvent) is 2%, while the solubility of Al (solute) in Si (solvent) is 0%. Explain why. Si r = 0.117 nm Diamond Electronegativity = 1.8 Valence = +4 ΑΙ r = 0.143 nm FCC Electronegativity = 1.5 Valence =+3 The Al and Si alloy shows only partial solubility.
