As an Art History major, you are forced to endure “discussion”, a third meeting every week when you go over what you learned in lecture during ARTH100. Every now and then, after meeting in Davis 212, a small classroom adjacent … Continue reading
The article that I read about acid rain showed the connection between chemistry, biology, and environmental science. It also connected to a class that I took last spring, called Coastal Zone Management, which I really enjoyed. The story of how … Continue reading
In a Smithsonian article by Devin Powell, the discovery of vanillin in rock in Northern Italy. The rock contains important information about soils from hundreds of millions of years ago. As the name suggests, vanillin, an organic compound, is molecularly … Continue reading

It was surprising to hear that water in it’s neutrality can act as an acid or a base, by either donating or accepting a … Continue reading
Last weeks lecture on acids and bases was extremely fun and interesting! It was great to see how chemistry is so inherent in our daily lives, and how many common bases (substances that accept a proton) such as lime water … Continue reading
As we learned in class last week, hydrochloric acid (or stomach acid) is extremely acidic. It has a ph of between 3 and 1 making it almost as acidic as battery acid. If it were outside of our stomachs, it … Continue reading
As we learned in class, pH follows a scale from 0 to 14 with 0-7 representing acidic solutions and above 7 representing basic solutions. Acids and bases can neutralize each other sort of like an average of two numbers. Though … Continue reading
This week we learned about how the anthocyanin and flavonol pigments in red cabbage act as indicators. The anthocyanins turn reddish pink under acidic conditions and blue under more basic conditions, whereas the flavonols were colorless under acidic conditions and … Continue reading
After our lab on Tuesday where we used red-cabbage paper as indicator of pH, I was interested in learning more about anthocyanins, or the chemical that makes the paper turn blue or pink in the presence of bases or acids. … Continue reading
Last class we saw for ourselves that water and oil do not mix. This is due to the fact that water is polar and oil is non-polar. Water molecules form strong hydrogen bonds with each other and are not as … Continue reading
