Tanya and Jon want to see if baking soda or sugar dissolves faster in water. Tanya adds 500 g of baking soda to 500 mL of room- temperature water. At the same time, Jon adds 500 g of table sugar to 500 mL of room temperature water. Both students start stirring the
mixture they made. In less than a minute, all of the sugar in Jon's mixture has dissolved. Tanya keeps stirring her mixture of baking soda
and water, but after 5 minutes, some of the baking soda still hasn't dissolved. Even if Tanya kept stirring her mixture all day, the remaining
baking soda would not dissolve. What explains this result?
