WebLet's say, we have a sample of pure water at 50 degrees Celsius, and our goal is to calculate the pH. Pure water is a neutral substance which means the concentration of … WebFor example, let's say a solution is formed at 25 degrees Celsius and the solution has a pOH of 4.75, and our goal is to calculate the concentration of hydronium ions in solution, H3O+. One way to start this problem is to use this equation, pH plus pOH is equal to 14.00. And we have the pOH equal to 4.75, so we can plug that into our equation.
