Explanation: … WebThen you convert it to pH. In pure water at room temperature the K w value tells you that: [H +] [OH -] = 1.00 x 10 -14. But in pure water, the hydrogen ion (hydroxonium ion) concentration must be equal to the hydroxide ion concentration. For every hydrogen ion formed, there is a hydroxide ion formed as well. 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. small claims court new york forms
