WebJan 30, 2024 · Solve for pH: pH = − log10[H3O +] = − log10(0.023) = 1.64. Step 2: To accurately draw our titration curve, we need to calculate a data point between the starting point and the equivalence point. To do this, we solve for the pH when neutralization is 50% complete. Solve for the moles of OH- that is added to the beaker. WebSo let's go ahead and look at all the possible scenarios for these three things. We're going to start with the simplest possible scenario, which is that pH is equal to pK_a. When pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one.
