Why do strong acids 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.
What happens to pH as the concentration of a weak acid increases?
If the concentration of the weak acid decreases, the concentration of the H+ ions reduces, which means the concentration of hydroxide ions is more than that of H+ ions.. Causing the pH to increase. pH is a measure of the concentration of the hydronium ion in solution.
Does a higher concentration make an acid stronger?
The higher the concentration of H plus ions, the more acidic the solution and the lower the concentration of H plus ions, the less acidic the solution. And similarly, the basic strength of a solution, it depends on the concentration of OH minus ions.
When H3O+ is added what happens to the equilibrium?
Adding H3 O+ ions will reduce the pH, making the substance more acidic. Adding more OH- ions increases the pH, making the substance more basic. For reactions that have OH- ions in the product side: Increasing the pH will increase the number of OH- ions, so the equilibrium will shift to the left.
Why is react with weak acids slower than strong acids?
If a strong acid is used, the rate is fast as the high concentration of H + ions increase the collision frequency. With a weak acid, the rate is slower, as few H + ions are available to react.
What happens when you increase the concentration of an acid?
Because increasing the concentration of HCl acid solution also means an increase in the number of hydrogen and chloride ions, collision between the reactant particles increases as well, resulting in more products-hydrogen gas. With more production of hydrogen gas in the confined test tube, pressure will build up.
Can a weak acid be concentrated?
It is perfectly possible to have a concentrated solution of a weak acid, or a dilute solution of a strong acid.
