Using a pH indicator strip will tell you that NaOH (sodium hydroxide) is a strong alkaline. This means it has a pH toward the top end of the pH scale, which ranges from 0 to 14. To calculate the exact pH, work out the molarity of the solution, then apply that to the formula for pH. WebAug 30, 2024 · Therefore to get the pOH we plug the concentration of OH - into the equation pH=-log (1.5075\times 10 -6) and get pOH=5.82. To get the pH we minus the pOH from 14. pH=14 - 5.82 pH= 8.18 Example 5: After adding 26 mL of 0.3 M NaOH Find the pH after the addition of 26 mL of NaOH. SOLUTION
