Acids, Bases, Ph.

What makes an acid an acid?
     An acid is an acid by its number on the Ph. balance. If its zero to seven it is an acid but if it is seven to fourteen it is a base.

Why is water neutral?
     Water is neutral because of the Ph. balance it is 7 which is neither acidic or basic. It is right in the middle. Water dissolves way more chemicals, minerals, and nutrient  than any other liquid.

How do antacids work?                                                                                                                                    Antacids work by increasing the Ph. balance. You may start to have problems when the Ph. balance in your stomach goes down and by taking an antacid you will increase your Ph. balance(raising it back to normal) and that's when you start to feel better.

My Attempt to Explain this Article (Dead simple’ way to see atomic structure)

The first image taken of how water coats surfaces can also be used to see other molecules like antibodies. A professor believes that most surfaces have a coat of water. Which affect the wear and tear properties on that surface. Although coatings of water on the surface are everywhere they are hard to study because they are constantly flowing around. However they discovered a way of keeping the moving water molecules in place to study them! They basically came up with a shrink wrap using graphene paper. They discovered that the first layer of water contains two water molecules and once that layer forms a second one comes into the picture with anther two molecules. It has the form of ice but this creates droplets. The reach searchers are now looking for a way to improve their technique to get better images.

Clinical Trial...
A clinical trial is a trial to evaluate the safety and the affects the medication may have on a person.  In a double blind placebo there is a group of people participating in the clinical trial.Some of them (half and half) receive the real medication while the other half is receiving a false medication that is practically the same thing but isn't (the placebo). The way people are chosen if they're taking the placebo or the real thing is randomly. The reason  for the double blind placebo clinical trail is so that the researchers could see if the medication is effective and it eliminates any possibility of what ifs. (By what ifs I mean by the effects and side effects it may have on us.(living breathing people))
