- In general, strong acids produce weak conjugate bases and weak acids produce strong conjugate bases A strong base is also fully ionised and is a good proton acceptor For example, the hydroxide ion is a strong base and readily accepts protons: OH– (aq) + H+ (aq) ⇌ H2O (l)

Strong and weak acids. Strong acids dissociate fully in water to produce the maximum number of H + ions. This means if you had one mole of hydrochloric acid (HCl) molecules, they would all...
Jan 7, 2011 · Strong and weak acids of the same concentrations react differently with reactive metals; This is because the concentration of H + is greater in strong acids compared to weak acids; The greater H + concentration means that more H 2 gas is produced . The diagram shows the reaction of 0.1 mol dm-3 of a strong acid (HCl) with Mg.
Weak acids partially dissociate (or ionise) in water. This produces a solution with a low concentration of H + ions. This means that weak acids have pH values that are closer to the middle of the pH scale, whilst still being below 7, i.e. pH 4 - 6.
Sep 16, 2022 · Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid. HC 2 H 3 O 2 is an example of a weak acid: \[HC_{2}H_{3}O_{2}\overset{\sim 5\%}{\longrightarrow}H^{+}(aq)+C_{2}H_{3}O_{2}^{-}(aq) \nonumber \]
Jul 12, 2023 · In an acid–base reaction, the proton always reacts with the stronger base. For example, hydrochloric acid is a strong acid that ionizes essentially completely in dilute aqueous solution to produce \(H_3O^+\) and \(Cl^−\); only negligible amounts of \(HCl\) molecules remain undissociated.
A strong acid and a weak acid of the same concentration will react at different rates with the same metal. You can see the difference between a strong acid and a weak acid of the same concentration by looking at the reaction with magnesium. The strong acid reacts faster and you see more bubbles of hydrogen.
How to distinguish between strong and weak acid. Strong and weak acids can be distinguished from each other by their: pH value (using a pH meter or universal indicator) Electrical conductivity; Reactivity; pH value. An acid dissociates into H + in solution according to; HA → H + + A-pH value of a Strong Acid & Weak Acid Table
