Describe how the food tastes, smells and looks.

Acids and Bases
Instructions
Please complete the following steps for your discussion post and response.
Acids and bases can be found in many places including the kitchen. Acids like lemon juice can make foods taste sour. Basic or alkaline foods such as peas or almonds may have more of a bland taste.  As we’ve learned this week, an acid donates a proton and a base will accept a proton.
Choose three foods that you can find in your kitchen.
Describe how the food tastes, smells and looks.
Using this week’s resource, what is the pH of the various food you’ve consumed and how do they contribute to the acidity or alkalinity of the body-specifically discuss an organ or system in the body? You should include outside resources and cite them according to APA.
Are there specific conditions that might benefit by consuming more acidic foods or alkaline foods?
Please be sure to validate your opinions and ideas with citations and references in APA format.

Visit the DHMO website (http://www.dhmo.org/ (Links to an external site.)) and review the materials about the fact and dangers of dihydrogen monoxide.  Read the first page of the website and then on the left side review each of the following tabs:
 Dihydrogen Monoxide FAQ
 Enviro Impact of DHMO
 DHMO and Cancer
 DHMO Research
 DHMO in the Dairy Industry
 MSDS for DHMO
 DHMO Conspiracy
 Editorial: Truth about DHMO
Post a response thread about how the sharing of chemical information can be misleading. 
I am looking for 100 plus words.  Discuss and describe your opinion of this website, the day-to-day use of DMHO, and the importance of basic chemical literacy in our lives.  You will need to use some of the chemical naming that we have covered in the notes and videos to truly understand the meaning and identity of some substances in the DMHO website.
