pH for weak acids

[Clarice Chui 2C]

Why do solutions of weak acids have higher pH values than solutions of strong acids at the
same concentration?

[VioletKo3F]

Lower pH means a higher acidity and more H+ in the solutions. Stronger acids have a higher acidity and they also dissociate completely, meaning more H+.

[Zaynab Hashm 2I]

pH is a measure of the concentration of H3O+ or H+, so it basically measures the concentration of hydronium ions in a solution.

strong acids dissociate/ionize way more compared to weak acids, and therefore release more H+.

since pH measures the concentration of H+ in the solution;
1. stronger acids will have more H+ and the pH will be lower according to the formula pH = -log[H3O+]
2. weaker acid will have less H+ and the pH will be higher according to the formula pH = -log[H3O+]

[Tahlia Mullins]

Since pH is determines by the concentration of H3O+ ions in the solution, the greater protonation yields a lower pH, and strong acids are known to be 100% dissociated, meaning a higher concentration of H3O+.

[Alondra]

I think of acids as having more protons and a lower value in the 0-14 range while bases have less protons and a higher value.

Weak acids disassociate into a less concentrated solution of hydronium ions in comparison to strong acids. Since pH is the negative log of hydronium ion concentration; weak acids would have higher pH values (negative log is basically the logarithm of 1/[hydronium ion])
