How does pH of a strong acid compare with the pH of a weak acid?
i think a strong acid ionizes completely in water while a weak acid ionizes partiallly in water therefore the pH of a strong acid is greater than that of a weak acid The first part of your answer was correct, but the second was reversed. The pH of a strong acid is lower than the pH of a weak acid.
Would a strong acid have a lower pH level than a weak acid?
yes a strong acid would have a lower ph level
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.
How can one determine the pH of a weak acid?
To determine the pH of a weak acid, you can use a pH meter or pH indicator paper. Alternatively, you can calculate the pH using the concentration of the weak acid and its dissociation constant.
If you choose to change the pH of a solution very slightly should you add a strong acid or weak acid?
You should add a weak acid to change the pH of a solution very slightly. Weak acids will have a less dramatic effect on the pH compared to strong acids, allowing for more precise control over the pH adjustment.
What is the PH of the weak acid?
The pH of a weak acid depends on its concentration. A weak acid solution with a higher concentration will have a lower pH, while a lower concentration will result in a higher pH. The pH can be calculated using the acid dissociation constant (Ka) of the weak acid.
Is weak base on the pH scale is it 3?
any thing with a pH below 7 is an acid and anything with a pH above 7 is a base. So a weak base would be around 8
How do you know if an acid is weak?
An acid is weak if it has a PH of seven or higher.
What pH does a weak acid have?
A weak acid typically has a pH below 7 but greater than 0, due to the partial dissociation of the acid in water. The exact pH value depends on the specific acid and its concentration.
Is a chemical with a pH level of 4 a weak acid?
Not very weak, it is a moderately weak acid.
Does a weak acid ionize at pH 7?
A weak acid will partially ionize at pH 7, but the extent of ionization will depend on the specific weak acid and its equilibrium constant. The pH of a solution does not determine if a weak acid will ionize, but it can influence the degree of ionization based on the acid's pKa value.
Why the weak acid cannot be used as titrant?
If you are titrating a base, using a weak acid as titrant would lead to the formation of a buffer as you added the weak acid. The weak acid would react with the base to form the salt of the weak acid + water, and this would buffer any changes in pH, thus making the titration meaningless.
