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

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!

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

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

pH=“power of hydrogen” Acidic solutions taste sour, react with metals, and have more Hydrogen ions (H+) in solution. They have a pH of 0-6.9 Basic solutions taste bitter, feel slippery and react with oils and fats. They have more (OH-) ions in solution. They have a pH of 7.1-14 Acids and Bases can be determined by adding color indicators to solution.

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)

Gastric (stomach) juice In your lab notebook, LIST THE CHEMICALS FROM WHAT YOU THINK IS MOST acidic to LEAST acidic. Gastric (stomach) juice Distilled water Milk Vinegar Drain cleaner Rain water Baking soda solution Lemon juice Liquid soap ammonia Gastric juice: 1 Lemon Juice: 2.3 Vinegar: 2.9 Rain water: 5.6 Milk: 6.6 Distilled Water: 7 Baking Soda: 8 Ammonia: 11.9 Liquid Soap: 12 Drain cleaner: 14 https://www.youtube.com/watch?v=Xkrgw2CFwRs (chem academy pH explained) https://www.youtube.com/watch?v=LS67vS10O5Y (crash course pH)

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. 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)
