1. On Target? Do this on your Warm Up worksheet!
What is the difference between water (H2O) and Carbon (C)?

2. What is the difference between water (H2O) and Carbon (C)?
Water is a molecule (multiple atoms bonded)
Carbon is an element or single atom of element
Carbon can be a part of a LOT of different things!

3. For today Warmup Carbon pH Notes
Objective: I can explain how carbon moves between water and the atmosphere by observing and discussing this process.

4. BIG IDEA! How does carbon move from the ocean to the atmosphere?

5. pH=“power of hydrogen”
Acidic solutions taste sour, react with metals, and have more Hydrogen ions (H+) in solution. They have a pH of Basic solutions taste bitter, feel slippery and react with oils and fats. They have more (OH-) ions in solution. They have a pH of Acids and Bases can be determined by adding color indicators to solution.

7. BTB turns from blue to teal to yellow over a narrow pH range from about 7.5 (blue) to about 6.5 (yellow). Blue  yellow means more acidic, and pH drops (CO2 added)
Universal indicator shows more gradual changes. Seltzer water starts at a pH of about 4 (red for universal indicator). Shaking the seltzer causes CO2 to leave the seltzer, or exsolve. This decreases the acidity (raises the pH), and leads to a yellow color. If left out for a day or more, the water will change to a neutral color (blue green)

9. VOCAB WORDS!
Exsolve: the process where a substance separates from a solution
Sublimate: the transition of a substance from a solid to a gas without becoming a liquid first.

Universal indicator shows more gradual changes. Seltzer water starts at a pH of about 4 (red for universal indicator). Shaking the seltzer causes CO2 to leave the seltzer, or exsolve. This decreases the acidity (raises the pH), and leads to a yellow color. If left out for a day or more, the water will change to a neutral color (blue green)
