Which of the following is a proper procedure for creating a supersaturated solution of potassium nitrate if you have 100g of water and 80g of potassium nitrate available? Add all of the solute to 100g of water and stir for an extremely long time. Add all of the solute to 100g of water and heat it up past 48 degrees C. Add all of the solute to 100g of water & heat it up past 48 degrees C. Make sure everything dissolves, and then carefully cool it down below 48 degrees C. Add all of the solute to 100g of water & heat it up just over 35 degrees C. Once everything dissolves, cool it down to below 35 degrees C. It is impossible to make a supersaturated solution of potassium nitrate with 80g of solute & 100g of water.
