Ph of 5n naoh
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. WebMay 10, 2024 · For 0.1 m NaOH, pOH = -log [OH-] = -log (0.1) = 1 pH + pOH = 14, So pH = 13 Same way for 0.05 m NaOH, pOH = -log (0.05) = 1.3 pH = 14 - 1.3 = 12.7 PH of 0.1M …
