The statement indicating that 'Flat temperature solubility profile is preferred to avoid Ostwald ripening' is TRUE.
<h3>What is Ostwald ripening?</h3>
The expression 'Ostwald ripening' refers to the process observed in solids/liquids that modifies the non-homogeneous molecular structure.
For example, 'Ostwald ripening' describes how different crystals can dissolve, and then form redeposits.
Temperature is a factor that alters Ostwald ripening properties by influencing their interfacial energy.
