Show my the pH chart by strong and weak acid?

Answer 1

A strong acid completely dissociates into an H+ ion and an anion.

pH is defined as pH = -log(H+ concentration)

So if you have 0.01 mole hydrochloric acid (HCl) per 1 mole solution, since

each mole HCl contributes a mole of H+ and a mole of Cl-

then you would have H+ concentration of 0.01

pH = -log(0.01) = -(-2) = 2, so the pH = 2

Note that higher H+ concentrations result in lower pH number

Answer 2

Sure! In general, strong acids have a lower pH (closer to 0) compared to weak acids. Strong acids completely dissociate in water, producing more hydrogen ions, which results in a lower pH. Weak acids partially dissociate, so they produce fewer hydrogen ions, leading to a higher pH compared to strong acids.
