The pH of milk black coffee, tomato juice, lemon juice and white egg are 6.8, 5, 4.2, 2.2 and 7.8 respectively. Calculate corresponding hydrogen ion concentration of each.

Answer:

Milk:\[[{{H}^{+}}]=Antilog\,[-pH]\] = Antilog [-6.8] \[=1.58\times {{10}^{-7}}M\] Black Coffee:\[[{{H}^{+}}]=Anitlog\,[-pH]\] = Antilog [-5] \[={{10}^{-5}}M\] Tomato Juice:\[[{{H}^{+}}]\]Antilog [-pH] = Antilog [- 4.2] \[=6.3\times {{10}^{-5}}M\] Lemon Juice:\[[{{H}^{+}}]\] = Antilog [-pH] = Antilog [-2.2] \[=6.309\times {{10}^{-3}}M\] White Egg:\[[{{H}^{+}}]\] = Antilog [-pH] = Antilog [-7.8] \[=1.584\times {{10}^{-8}}M\]
