bases and acids

Acid taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases.
Bases feel slippery, change litmus blue, and become less basic when mixed with acids. 
To change an acid to a base you have to increase  some of the ions to make it basic again.


How do ant acids work? Ant acids work by changing the acids in your body by changing  the ph levels to make the acid  a base. And what would make an acid an acid is that it has a higher level of hydrogen and the more basic it gets the more OH it has.

water properties article summary

This article is about how scientist have been studying properties of water by using  sheets of carbon and using tunneling microscopes to see how water coats the surface at room temp. They have discovered that water molecules are hard to study cause they do not sit still for very long "in constant Flux." To make the molecules stay still they accidentally they came across a technique to hold them still at room temp. using a thin layer of carbon mesh "Graphene" only one atom thick water molecules are held still under the mesh. the structures under this became more notice able in higher humidities. They had discovered that on mica the molecules were actually two molecules thick. they look like little islands. They are trying to use what the have discovered to study all surfaces like adhesion and lubricants. this study was provide by the u.s department of energies offices of basic energy science.

what i learned

What i learned from the clinical trails experiment yesterday was how to use the clinical trials web site to find different disease  and learn who does what how they are experimenting with vaccine and who is eligible for the trials. i learned they some times give several people medicine but only one person really got the medicine and they want to know who it affected with out the psychological effect. I also learned this definitions and what they mean and how they are applied in a study. The double blind experiment- means in an experiment procedure neither of the subjects know the critical aspects of the experiment. Placebo-  is a simulated medical intervention that can produce an effect because the thought not the drug they had received. Control is having the basic understanding of the experiment you are being part of. That is every thing i have learned from what we did yesterday.
