Question

Ionic solids generally become more soluble as water becomes _______ . Covalent compounds, like NH3, tend to become _____ soluble as the water becomes warmer.

Options:
Option 1: colder, more
Option 2: warmer, less
Option 3: colder, less
Option 4: warmer, more

Answer 1

Ionic solids generally become more soluble as water becomes warmer. Covalent compounds, like NH3, tend to become less soluble as the water becomes warmer.

Step-by-step explanation:

Ionic compounds generally become more soluble as water becomes warmer. This is because an increase in temperature allows for more kinetic energy, which in turn increases the rate of dissolution between the ionic solid and the water solvent. On the other hand, covalent compounds like NH3 tend to become less soluble as the water becomes warmer. This is because covalent compounds rely on intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, for solubility in water. When the water becomes warmer, these intermolecular forces become weaker, leading to decreased solubility of the covalent compound.
