WebSince the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2. Likewise, a solution of pH 12 would be 10 times more alkaline than a solution of pH 11. pH Calculations Involving HCl Solutions 1. Given the Wt% of an HCl solution, what is its theoretical pH value?

WebIt's somewhat contradictory to discuss pH as -log[H+], and then say that pH = -3.6 is possible. There is no way you can cram over 1000 moles of hydronium ions into a liter! The -3.6 value only makes sense if you explain that pH = - log (H+ activity), and that it is the deviation of activity from concentration that makes the value -3.6 possible. Web9.8 × 10 − 5MNaOH 0.101L = 9.7 × 10 − 4M The pOH of this solution is: pOH = − log[OH −] = − log(9.7 × 10 − 4) = 3.01 The pH is: pH = 14.00 − pOH = 10.99 The pH changes from 4.74 …
