Video summaries: Buffers, the acid rain slayer

Hello!

Acid rain is a solution that forms when sulfur dioxide reacts with water in the air to form “Sulfuric Acid.” This process is very common in the United States; to such a degree that many rivers and lakes were devastated by plant and animal life, although there were some exceptions; for example in the river “Clark Fork” where the damage from acid rain is less or imperceptible compared to other places, this because this river is “protected” by limestone, which provides calcium carbonate that acts as a natural buffer that prevents changes in pH.
