Lower Sec Science · Secondary 1 · Hard · Solubility

A student dissolves 20 g of a solid in 100 g of water at

40^\circ\text{C}

. The solubility of the solid at

40^\circ\text{C}

is 30 g per 100 g of water. What type of solution is formed?

An unsaturated solution, because less than 30 g is dissolved.
A saturated solution, because the solid stops dissolving.
A supersaturated solution, because more than 30 g is dissolved.
A suspension, because no solid dissolves.
