A strong acid is defined as one that dissociates completely in water (see the Related Questions link to the left for a list of the strong acids). That means for every mole of acid added, one mole of free H+ (or equivalently, H3O+) is present in the solution. The pH of solution is defined this way:
pH = -log10 [H3O+]
or in English, the pH is equal to the negative logarithm (in base 10) of the concentration of H3O+ in the solution (the concentration must be in units of Molarity (M), which is moles per liter).
Cf. 'Related questions' link just below this answer for more detailed explanation and examples of calculation.
What else can I help you with?
If you have a solution of a strong acid and a solution of a week acid of equal concentration and volume then the?
pH of the strong acid solution will be lower than the pH of the weak acid solution due to the stronger dissociation of the strong acid.
What is the process for calculating the pH of a strong acid solution?
To calculate the pH of a strong acid solution, you can use the formula pH -logH, where H represents the concentration of hydrogen ions in the solution. For a strong acid, the concentration of hydrogen ions is equal to the concentration of the acid. Simply take the negative logarithm of the hydrogen ion concentration to find the pH value.
How does the titration of a weak base with a strong acid affect the pH of the solution?
When a weak base is titrated with a strong acid, the pH of the solution decreases. This is because the strong acid neutralizes the weak base, leading to an increase in the concentration of H ions in the solution, which lowers the pH.
What pH represents is a strong acid?
a pH of less than 7
What is the pH difference between a strong acid and a weak acid n the pH scale?
Usually a strong acid will produce a lower pH, but not always. pH is not a measure of the strength of an acid (or base) but the acidity of a solution, which is dependent on both the strength of the acid or base and its concentration in the solution.
What would happen to the overall pH if you dumped a strong acid into a solution that was slightly alkaline?
The final pH of the mixture will depend on how much of the strong acid you add. The initial amount of acid will neutralize the alkaline solution, and if there is enough of the strong acid, the final pH will then become acidic, i.e. pH < 7.
What happens when the pH solution is lower?
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.
Is it possible for a strong acid and a weak acid to have the same pH?
Yes In theory, you could have a very weak solution of a strong acid and a stong solution of a weak acid and they would have the same pH.
PH is 3 Is the solution a very dilute solution of a weak acid or a more concentrated solution of a strong acid Propose a way to answer the question?
A pH of 3 indicates that the solution is acidic. To determine if it is a very dilute solution of a weak acid or a more concentrated solution of a strong acid, you could perform a titration experiment to measure the exact concentration of the acid present. This would involve adding a base of known concentration to the solution until it reaches a neutral pH, allowing you to calculate the initial acid concentration.
How much pH is in strong acid?
pH is not a measure of how strong an acid is. pH is a measure of the concentration of hydronium ions in a solution, which is dependent on both the strength of the acid or base and its concentration in a given solution.
Is the pH of 25 acetic acid higher than 0.25 hydrochloric acid?
Yes, the pH of a 25% acetic acid solution is higher than that of a 0.25M hydrochloric acid solution. Acetic acid is a weak acid, so its pH will be higher compared to hydrochloric acid, which is a strong acid.
What is the pH of a 3 percent acetic acid solution?
The pH of a 3% acetic acid solution is around 2.4. Acetic acid is a weak acid, so it does not completely dissociate in solution. This results in a pH lower than that of a strong acid at the same concentration.
