WebMar 14, 2024 · Example 1: Calculate the pH of a 0.200 M HCl solution. HCl solutions are strong acids, so we can already expect a pH of less than 7. Using the 0.200 M HCl as the [H+] (concentration of hydrogen ions) the solution is as follows: pH=-\log { \left [ { H }^ { + } \right] } = \log (0.200) =0.70 pH = −log[H +] = log(0.200) = 0.70 WebSteps in Determining the Ka of a Weak Acid from pH Step 1: Write the balanced dissociation equation for the weak acid.

WebApr 24, 2024 · Calculate the concentration of hydrogen ions with the formula [H+] = 1/ (10^pH). The units for concentration are moles per liter, where a mole is a set of particles whose quantity equals 6.02 x 10^23. For example, if the pH of the solution is 2.29, the concentration is [H+] = 1/ (10^2.29) = 5.13 x 10^-3 moles/liter.
