Carbonic Acid


We know that pH is a measure of H+ ions (for acids) 
or OH- ions (for bases).
So how does adding CO2 to a water-based liquid, manage to change its pH?


What is carbonic acid, and what does it do?

  1. Carbonic Acid: How does it work?
  2. Bozeman Science: Ocean Acidification video
  3. Wikipedia: Carbonic Acid (way too much detail, but a good overview)


What happens when acids react with calcium carbonates?

Chemistry in the Ecosystem

What will we be learning in the Chemistry unit? -Understanding atomic structure and the periodic table in (more) depth -Relating this to our understanding of soil and plant nutrition -Ions, anions and chemical bonding & how this impacts how plants take up nutrients -Elemental classification: metals, non-metals and metalloids -Chemical reactions: Photosynthesis and Respiration -pH. What it means and how it impacts plant growth. Let's start with refreshing you on the basics: Here are the links you'll need for the worksheet: 1. Scale of the Universe 2.    Khan Academy: Atoms Your Plant Nutrient Poster 1. Select one of the 17 essential plant nutrients Hydrogen Boron Carbon Nitrogen Oxygen Magnesium Phosphorus Sulfur Chlorine Potassium Calcium Manganese Iron Nickel Zinc Copper Molydendum 2. Make a small, A5 poster which clearly states: a) The elements name, symbol, atomic mass and electron shells b) A diagram of the atomic structure ...

HELPFUL PLATE BOUNDARYS - click down the bottom to move onto other types A copy of the assignment can be found here In this assignment you will explore data about: - Bathymetry (shape of the ocean floor) - Topography (shape of the continents) - Age of the Ocean floor - Volcanoes  - Earthquakes  to make decisions about what sort of plate boundaries are where. The skills you will use during this assignment are comparable to those used by geologists and geo-physicists to understand the processes which shape the Earth  - if you enjoy the assignment and the unit - maybe there's a career in Earth Sciences for you! HOW TO GET STARTED: 1. Download   Google Earth    on your device. 2. Download (and save to your device) the   Google Earth data files #1   and  Data #2: EARTHQUAKES  and Data #3 VOLCANOES 3. Open up both of the files in Google Earth.  4. Begin following the instructions on Page 1 of your assignment.  Note ho...
