pH, pOH, and the pH scale (article) Khan Academy

WebOne 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. That gives us pH plus 4.75 is equal to 14.00. And solving for the pH, we get that the pH is equal to 9.25. WebIf you want an accurate measurement you will typically use a device called a pH meter§. There are also chemicals called pH indicators that can be used. These chemicals are often bound onto small strips called pH paper than change color to give you an estimate of the pH. react native placeholder font size
