This means that the pH values of strong acids are lower than that of weak acids, which explains why the rate of reaction of strong acids with substances (such as metals, metal carbonates etc) is ...
Sep 16, 2022 · Strong and Weak Acids. Except for their names and formulas, so far we have treated all acids as equals, especially in a chemical reaction. However, acids can be very different in a very important way. Consider HCl(aq). When HCl is dissolved in H 2 O, it completely dissociates into H + (aq) and Cl − (aq) ions; all the HCl molecules become ions:
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.
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 in a shorter time. The diagram shows the reaction of 0.1 mol dm-3 of a strong acid (HCl) with Mg.

Ethanoic acid is a typical weak acid. It reacts with water to produce hydroxonium ions and ethanoate ions, but the back reaction is more successful than the forward one. The ions react very easily to reform the acid and the water. At any one time, only about 1% of the ethanoic acid molecules have converted into ions.

Jul 12, 2023 · Thus the conjugate base of a strong acid is a very weak base, and the conjugate base of a very weak acid is a strong base. The conjugate base of a strong acid is a weak base and vice versa. We can use the relative strengths of acids and bases to predict the direction of an acid–base reaction by following a single rule: an acid–base ...
