Acids bases and PH level

I really enjoyed the antacid lab. It was fun to find out how antacids work and watch them work. Antacids work by turning the acid in your stomach into a base or more basic then it was. Anti-acids work by taking the hydrogen atoms from the stomach acid and makes a molecule using the hydrogen. On the PH scale acids are lower and bases are higher. the PH scale goes up to 14 which is the most basic which would be cleaner and down to 1 which would be like battery acid. 7 is neutral for example water. Something is an acid when it has more negative parts than positive.  Something is a base when the positive parts outnumber the negative parts. This what I have learned from the antacid lab. See My post tums and such for the lab results.

water, water, water

water, water, water, water is everywhere. Water takes up more then 70% of the earth. That is 400 billion-billion Gallons of water on earth. that's a lot of water. water has many different properties Adhesion, Cohesion, Solvent, Specific heat, and surface tension. 

First there is adhesion it is the attractive force between molecules in one phase  and different molecules in another phase. Adhesion is what made it so we could move water from one cup over 3.4 meters to another cup. To do this we held the cup with the water up in the the air. then we poured it down a tight string to another cup. The molecules in the string and the molecules in the water stuck together and made it possible for the water to slide down the string to the other cup.


Next there is cohesion. Cohesion is the attractive forces between similar molecules in the same phase. Cohesion is what made it possible to stack 55 drops of water on one penny before it started flowing off the penny. There was a huge bubble on the penny and it was hanging over the edge of the penny but cohesion caused The water molecules to  stick together so it didn't fall over the edge. Another property that made putting 55 drops of water on one penny possible is surface tension. Surface tension is a property of the surface of a liquid that allows it to resist an external force.

Another is solvent. A solvent is a liquid which dissolves another substance without any change in its chemical composition. Hydrophilic is water loving. it will dissolve in water. hydrophobic is water fearing. It will not dissolve in water. For example oil. Oil will not dissolve in water it just floats on top. that's why the bp oil spill was so serious. If oil was water loving the oil spill wouldn't be a problem.

The last property of water is Specific heat. Specific heat is the amount of heat needed to raise the temperature of a 1 gram sample of water by one degree celsius. This makes it so the temperature in the ocean doesn't change from night and day.

tums and such

Hi how are you. I'm good. what are you up to? I'm writing this blog. . . today i learned about double blind study. That is a clinical trial that both the doctors and the patient don't know who got the real drug and who got the placebo. A placebo is a sugar pill they give people in the study as the control. the control is the variable that doesn't change. So you walk into an office with a friend for A clinical study for an male pattern hair loss drug. They give both of you some pills that you have to take each day. After a week you hang out again one of you nothing is happening. The other is freaking out because he is seeing things but his hair is looking nice. Who got the real drug and who got the placebo? The guy who got the placebo is the one that nothing is happening too. The other guy got the real drug. The doctors will look at this for the results of the study to find the drug works but it makes you see things.
