WebTo find the pH we will use the following formula using the given acid concentration: pH = – log (4.1 x 10 -4 M) Note: The number of sig figs will be the number of decimal places pH … WebMay 2, 2024 · [H +] = 3.2 x 10 -9 M Example 3 Find the pH if the H + concentration is 0.0001 moles per liter. Here it helps to rewrite the concentration as 1.0 x 10 -4 M because this makes the formula: pH = - (-4) = 4. Or, you could just use a calculator to take the log. This gives you: Answer: pH = - log (0.0001) = 4
