The egg-white is alkaline (basic), while the yolk is slightly acidic. The white is more alkaline in free-range chickens, partly due to their diet.
This pH is slightly basic.
Acidic
Egg white is slightly alkaline, with a pH ranging from 7.6 to 8.0, due to the presence of basic amino acids such as lysine and histidine.
Here is a website that tells what the pH of eggwhites are, I haven't seen anything about total pH, perhaps some nice person will steer us in the right direction. http://newton.ex.ac.UK/teaching/CDHW/egg/#white
Eggs are slightly acidic with a pH ranging from 7.6 to 7.9. The acidity of eggs can vary depending on factors such as the age of the egg and the feed of the chicken.
Eggs are slightly acidic, with a pH range of 6.5 to 8.0. This is due to the presence of amino acids and other compounds in the egg whites and yolks.
Its the stringy white thread that holds a fresh eggs yolk to the first white in a birds egg - best seen on chickens eggs - this disappears as the egg ages
To determine if an egg is fresh, shake it gently next to your ear. If you hear a sloshing sound, the egg is likely not fresh. If you don't hear anything, the egg is fresh.
The small white bit next to the yolk of an egg is call chalaza. This is a strand of heavy protein that helps to keep the yolk centered in the albumen (white/clear part of an egg). This chalaza disappears as the egg get older and is more visible when you buy very fresh eggs.
Egg whites are the least acidic among milk, lemon, tomatoes, and egg whites. Lemon and tomatoes are acidic in nature, while milk can vary in acidity depending on its processing and fat content. Egg whites have a neutral pH level and are not acidic.
After 6 hours, egg white will be partially digested by pepsin, which breaks down proteins into smaller peptides. The hydrochloric acid will continue to provide the acidic environment necessary for pepsin to function optimally. Overall, there will be a decrease in the amount of egg white and changes in its composition due to digestion.
The egg white (albumen) will turn litmus paper blue due to its alkaline pH. The yolk, on the other hand, is acidic and will not have an effect on litmus paper.
