Phosphoric acid












Most of us know that coke is bad for our teeth because of the high sugar content, but is it just because of the sugar? I looked at the ingredient list and found this: Phosphic acid.

This acid is an inorganic acid with the chemical formula H3PO4. 
It is used to make phosphate salts for fertilizers, in dental cements, in the preparation of albumin derivatives, and in the sugar  industries as it serves as an acidic, fruitlike flavoring in food products.
Although it is an acid and it can be corrosive when the concentration is higher than 85%, when in an aqueous solution it is clear, colorless, odorless and most importantly it isn’t toxic.


If you are interested on further properties of coke and what Phosphic acid can do, check out the video links below, you’ll be blown off your chairs!
A simple but amazing experiment you can do at home with Coca-Cola and plastic utensils. Shows how harmful phosphoric acid, which is in many sodas, can be.
