Answer to Question #115339 in Physical Chemistry for Alexis

Question

You added 1 tablespoon of baking soda (14.4g) to 1/4 cup of water (60g). This was too ugh back soda (or not enough water) for all the baking soda to dissolve. One way to get all the baking soda to dissolve would be to add more water. *The solubility of baking soda in water at 20 degrees is very low only 9.6g NaHCO3/100g water. How many grams of water at 20 degrees would you need to be used to completely dissolve the tablespoon (14.4g) of baking soda?

Answer 1

V(H₂O) = (100 / 9.6) × 14.4 = 150 mL.

Answer: 150 mL.
