WebJul 30, 2024 · The pH scale, which measures from 0 to 14, provides an indication of just how acidic or basic a substance is. Most parts of our body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). If foreign strong substances dramatically change this pH, our bodies can no longer function properly. WebJan 30, 2024 · Use the pH equation which is: pH = − log[H3O +]. 0.055 M HBr, HBr is a strong acid [H 3 O +] = 5.5 X 10 -2 M pH = -\log (5.5 X 10 -2) = 1.26 2. Use the pH equation pH = − log[H3O +] and pK w equation pKw = pH + pOH = 14. 0.00025 M HCl, HCl is a strong acid [H 3 O +] = 2.5 X 10 -4 M pH = -\log (2.5 X 10 -4) = 3.6 Then solve for the pOH:
WebMar 2, 2024 · pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. WebMar 23, 2024 · The pH is thus –log (0.100) = 1.000. The formula for pH is pH = -log [H+]. This means pH is the negative base 10 logarithm (“log” on a calculator) of the hydrogen ion concentration of a solution. To calculate it, take the log of the hydrogen ion concentration and reverse the sign to get the answer.
