What does the strength of an acid effect?
The strength of an acid varies from solvent to solvent. An acid which is strong in water may be weak in a less basic solvent, and an acid which is weak in water may be strong in a more basic solvent. According to Brønsted–Lowry acid–base theory, the solvent S can accept a proton. , which is more acidic than water.
Why does a stronger acid react faster?
Strong acids dissociate fully in water to produce the maximum number of H + ions. 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 higher than that of weak acids.
How does the strength of an acid relate to the concentration?
The strength of an acid relates to the number of free ions in solution while the concentration of an acid relates to the number of ions that it contributes to a solution.
Does acid increase rate of reaction?
If the concentration of acid (a reactant) is increased, the reaction proceeds at a quicker rate.
What is meant by strong acid and weak acid?
Strong acids are those that are completely ionized in body fluids, and weak acids are those that are incompletely ionized in body fluids.
Do strong acids have higher concentration?
If ANY acid has a high concentration then this will consequently increase the hydrogen ion concentration making the acid ‘stronger’. Strong acids dissociate 100\% into ions in solution, whereas weak acids only partially dissociate into ions.
What factors increase the rate of reaction?
There are four main factors that can affect the reaction rate of a chemical reaction:
- Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction.
- Physical state of the reactants and surface area.
- Temperature.
- Presence of a catalyst.
