A student dissolves 20 g of a solute in 100 g of water at 30 °C to form a clear solution. She then adds another 10 g of the same solute and stirs, but some solid remains undissolved. What does this show about the solution at 30 °C?
- The solution is saturated at 30 °C
- The solution is unsaturated at 30 °C
- The solute is insoluble in water at 30 °C
- The solution is a suspension at 30 °C
