    If the solution contains 35 grams of NaCl per 100 grams, the solution is unsaturated

    Explanation:

    Step 1: Data given

    Solubility of NaCl at 20 °C = 35.89 grams NaCl per 100 grams of water

    Solubility of NaCl at 30 °C = 36.09 grams NaCl per 100 grams of water

    Saturated Solution: A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom.

    Unsaturated Solution: A solution (with less solute than the saturated solution) that completely dissolves, leaving no remaining substances.

    Supersaturated Solution: A solution (with more solute than the saturated solution) that contains more undissolved solute than the saturated solution because of its tendency to crystallize and precipitate.

    Step 2:

    The solubility of NaCl at 25.0 °C: 35.89 < X < 36.09

    If the solution contains 35 grams of NaCl per 100 grams, the solution is unsaturated
