A bicarbonate/carbonic acid buffer is present in Coca-Cola, human blood, and chickens. However, chickens also combine the carbonate in their blood with calcium ions to create calcium carbonate for their eggshells. Since chickens do not sweat, they pant in hot weather. Panting helps to reduce the acidity of the blood by blowing out carbon dioxide. What effect would this have on the pH of their blood and the strength of eggshells they produce
