Part A A KCI solution containing 44 g of KCl per 100.0 g of water is cooled from 70 °C to 0 °C. What happens during cooling? O At 70 °C the solution is unsaturated, but by 0 °C the solution is saturated; therefore a precipitate will form. O At 70 °C the solution is supersaturated, but by 0 °C the solution is unsaturated; therefore no precipitate will form. O At 70 °C the solution is supersaturated; therefore a precipitate will form upon cooling. O At 70 °C the solution is unsaturated, and at 0 °C the solution is also unsaturated; therefore no precipitate will form. Request Answer Submit
