Students continue work on Acid-Base activity using the marshmallows. What is the difference between how a strong base and a weak base dissociate? There will be a quiz on Th 3-3-11 on acids and bases and the pH scale. The map below shows the pH of precipitation (rain/snow) across the US. Note that all rainwater is slightly acidic (how do you know this?). Why would the industrial NE have rain that is called “acid rain?”
