The pH of a solution is equal to the negative logarithm of the hydronium ion (H3O+) concentration. Example 1:Find pHfrom [H3O+]. In a 1.0 L sample of 0.1 M hydrochloric acid (HCl) the concentration of hydronium ions is 1 × 10-1. What is the pH? pH = − log [H3O+] pH = ...
and it's one on which our lives depend. The process is this: In a solution, molecules of a solvent, such as water, migrate across a barrier from the side containing a lower concentration of a particular solute (a minor component of the solution) to one containing a higher concentration o...
