pH Formula - Meaning, Equation, Calculation and Solved …

WebIf the pH value is less than 7, the solution is acidic. If the pH value is equivalent to 7, the solution is neutral. If the pH value is more than 7, the solution is basic. Numerical. Calculate the [OH –] concentration of a solution having pH of 4.42; Given, pH = 4.42. We know that, pH + pOH = 14. 4.42 + pOH = 14. pOH = 14 – 4.42. pOH = 9.58 ... Web1. The first thing to do would be to see which equation fits in best with the question asked. Here we are looking for [H+] so the best equation would [H+]= 2nd log (-pH) since we already have the value of pH. 2. The next step would be to plug in the given information to the equation. Here we have pH so we would plug 3 into the equation for pH.
