acid ph and bases.



I learned that acids are mostly are a sour taste. And are corrosive to metal. They become less acidic when mixed when a base. Acids react with bases to neutralize their properties.  The color that acids mostly are is redish color. Bases are slippery, and are blue. They become less basic when mixed with an acid, and conducts electricity. I just learned that water behaves both as a acid and base. When an acid and base are together, they are neutralize. thats about what i've learned from ph, acid and base lab.

Dead simple way to see atomic structure: current event

http://www.futurity.org/science-technology/dead-simple-way-to-see-atomic-structure/


This article made me really think about molecules and how to learn how to pin down a molecules like the scientist in the article. He figured out how to hold down moving molecules under room temp but he learned this by accident.How cool is that to do that by accident. Heath and Colleagues scientists, thought anomalies were water moleules trapped under grapheme, but found out that it really was water molecules. Then they wanted to discover shrink wrap, and figured out that the structures noticeable at higher temperatures. But then they become unnoticeable in dry conditions. You never know you just may figure out a new world....by accident.
