The hydronium ion concentration of vinegar is approximately M. What is the corresponding value of the pH?
What is the hydronium ion concentration of blood, the pH of which is 7.3 (slightly alkaline)?
Water exposed to air contains carbonic acid, , due to the reaction between carbon dioxide and water, as shown. Air-saturated water has a hydronium ion concentration caused by the dissolved of M, about 20 times larger than that of pure water. What is the pH of the solution at ?
