Web16 de mar. de 2024 · PH is defined as the negative of the base-ten logarithm of the molar concentration of hydrogen ions present in the solution. The unit for the concentration of hydrogen ions is moles per liter. To determine pH, you can use this pH to H⁺ formula: \small\rm pH = -log ( [H^+]) pH = −log( [H+]) 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. famous footwear outlet grove city
