pH lab

From this lab i learned quit a bit that i didn't know before. I learned that acids release hydrogen ions, and bases release hydroxide ions, and when they mix they make water. which is why when acids and bases mix, they get a pH level of somewhere around 7. 7 is the pH level of distilled water. The further down on the pH scale something gets, the more acidic it is. And the higher up means that it's a base. The lower the pH number means the more Hydrogen Ions are in it. And the higher means the more Hydroxide Ions. Even though i learned quite a bit from this lab there's still some i wish i know more about. For example i know that soda is acidic but i'm not sure how acidic. And I need to learn more about what it's okay for people to have and what exactly is too much of an acid or base for a human.

Article Review: Calories and Alzheimers

This article is all about how lower calorie consumption can not only slow down the effects of aging on your body, and how it may be able to prevent Alzheimer's Disease if you consume at least thirty percent less calories than normal. Many people who are trying this method of preventing the disease say that even though there is some weight loss involved, it's worth it to have a less chance of getting Alzheimer's. Eventually they want to invent a pill that levels out the calories in your body to prevent the disease. It was a pretty interesting article. I think it's surprising that Calories can have an effect on the likeliness of getting a disease. I learned quite a bit from it.
