Why is the reaction rate of a given metal with a stronger acid is faster than with weaker acid?

Which one required more volume to produce neutral solution, a strong acid or strong base,or are they just the same? Can you explain it to me please coz I can't figure it out.

Thanks in advance!

The net reaction is between hydronium, H3O+, ions and the metal, producing metal anions and hydrogen gas. A strong acid solution has a higher concentration of hydronium ions that a week acid. The rate is higher when the concentration of any one of the reactants is higher.

For part 1, then why is the reaction rate of a given metal with HCl is faster than with acetic acid?

For part 2. how about 1.0M HCl and 0.5MNaOH? Which one needs more volume to produce a neutral solution?

1. HCl is highly dissociated since it is a strong acid. It produces a high concentration of hydrogen ions, H+(aq) in a water solution which are the same as hydronium ions, H3O+. Acetic acid, HC2H3O2, is made of molecules that do not dissociate. Its concentration of hydrogen (hydronium) ions is low. That is why acetic acid reacts more slowly than HCl with metals.

Why does more hydrogen ion results a faster reaction rate?

Thanks

I got it. Thanks for both of you :)

The reaction rate of a given metal with a stronger acid is faster than with a weaker acid because the strength of an acid is determined by its ability to donate hydrogen ions (H+). A stronger acid has a greater concentration of H+ ions, which increases the likelihood of a successful collision between the metal and the acid. This results in a faster reaction rate.

To determine which one requires more volume to produce a neutral solution, we need to consider the concept of titration. In titration, a measured volume of an acid or base solution is added to a flask containing the opposite solution until the reaction reaches a neutral point, known as the equivalence point. At this point, the moles of acid and base are equal, and the resulting solution is neutral.

In general, the volume required to produce a neutral solution depends on the stoichiometry of the reaction. This means that it depends on the balanced chemical equation and the ratio of moles between the acid and base.

However, it is important to note that the strength of the acid or base does not directly correlate with the volume required to reach a neutral solution. The volume needed will depend on the molarity (concentration) of the acid or base and the stoichiometry of the reaction. A strong acid or base may require less volume to neutralize a weaker acid or base solution if its molarity is higher.

In summary, the volume required to produce a neutral solution depends on the molarity and stoichiometry of the acid and base involved, rather than their strength.

I don't agree with the supposition that a given metal will react faster with a strong acid than a weak one. I think the supposition is based on the fact that weak acids are not completely ionized; therefore, there are more hydrogen ions in a strong acid (one that ionizes completely). And the sentence, as you have expressed it, may intend to talk about acid strengths (that is one is more concentrated or dilute than the other). If that is the intent, then a metal reacts faster with more concentrated acids generally because they contain more hydrogen ions. But no general rule can be observed for that. For example, concentrated H2SO4 is hardly ionized at all since there is little water to form the hydronium ion. For the second part of your question, the answer is not obvious either because you don't specify how much of one versus the other or the concentrations. Volume for volume, and comparing the same kind of acid (monoprotic or diprotic or triprotic) as well as the same strength, then a neutral solution is present when the volume of one solution equals the volume of the other solution.
