Problem: Spontaneous dissolving under standard-state conditions at 25°C occurs with a mix ofA. KNO3 & n-butanolB. I2 & CH2Cl2C. CaCO3 & hexaneD. acetone & KNO3 

FREE Expert Solution

To determine which mixture will result in a spontaneous dissolving under standard-state conditions at 25°C:


We’re going to use the theory “likes” dissolving “likes” which states that the solvent can only completely dissolve the solute if they share similar polarity and intermolecular forces of attraction (IMF)
