Why do strong bases make more H30+?

Postby Madeline Ellmore 2C » Thu Jan 13, 2022 8:05 pm

Can someone clarify/explain why strong bases make more H3O+? He said it in lecture 5, but I am still a little confused. Thank you!

The dissociation of a strong base(B) is given by the reaction: BOH <=> BH+ (aq) + OH- (aq). A strong base means it will dissociate in a solution and therefore produce more OH- ions. When he talked about weak bases in lecture, we found that they did not dissociate very well in water because we ended up with a high concentration of reactants in comparison to a low concentration of products, meaning little OH- was formed. As for strong acids, they will produce more H3O+ ions in comparison to weak acids, because strong acids have strong dissociation when placed in a solution [the reaction is HA (aq) + H2O(l) <=> H3O+ (aq) + A- (aq)].

Furthermore, the degree of which certain acid or base can dissociate in H2O determines if it is strong or weak. Strong bases dissociate into OH- + [some compound] to almost completion (in other words, the reaction heavily favors the products). The same applies for strong acids. Weak bases and weak acids usually heavily favor the reactants (in other words, almost none of the original weak acid/base dissociates).

Strong bases make more H3O+ because strong acids and bases dissociate fully, resulting in more product.

In dissociation reactions with strong acids or bases, they are able to ionize completely in water. This means that the reaction favors the products. Weak acids and bases usually heavily favor the reactants because they can only partially dissociate. In other words, this means that compared to the dissociation reactions of strong acids and bases, very little of the original weak acid or base actually dissociates.

Strong bases are more willing to accept protons. So strong bases causes there to be more OH- in a solution.

It is because they dissociate completely while weak acids and bases do not

Strong bases dissociate 100% in water to produce hydroxide ions (OH-), while strong acids also dissociate 100% in water but they produce hydronium ions (H3O+).

Strong bases completely dissociate in aqueous solutions, producing a high concentration of hydroxide ions. The concentration of hydroxide ions (OH-) produced by a strong base can be used to calculate the pOH of the solution, which can then be converted to the pH of the solution. While the pH of strong bases is high, it is important to note that they do not actually make more hydronium ions (H3O+) because pH is the negative logarithm of the concentration of H3O+. A pH of 14 represents a very small concentration of H3O+.

They fully dissociate into OH-

Strong bases fully dissociate in the solution while weak bases don't. Because they fully dissociate they also create more H3O+ since that is what forms when a base dissociates into water.

Strong bases produce more OH- in a solution because they fully accept protons. Strong acids produce more H3O+ in solution because they dissociate fully. This differs from weak acids/bases because weak acids/bases only deprotonate/protonate partially.

Strong bases undergo complete disassociation while weak bases only undergo partial disassociation.
