Acid rain (carbonic acid) is formed when CO2 emissions are combined with water in the atmosphere. Here we replicate this process on a more rapid scale. Dry ice is added to several beakers containing an acid/base indication and sodium hydroxide (NaOH, base). Upon formation of the carbonic acid, the indicator turns colors which indicates a shift from a pH of 11 to a pH of around 3.

  • This is nature way of removing co2 from the atmosphere. Rain absorbs co2 to form weak carbonic acid. The weak acid is returned to the carbon cycle or is held in the oceans. When the Sun enters a grand maximum warming the planet, co2 is released from the oceans.

  • Carbonic acid is not mentioned in the bible and therefore does not exist, nor do dry ice or Ph indicators.

    Chemistry is the devil! Your school should know that.

  • Acid rain is actually Sulfur Dioxide or Trioxide.

  • Wow, they change colors..

  • Carbonic acid is tasty.
