Examine the false statement.
Weak acids always have a high pH.
Select the rewording that makes the statement true.
A).Strong acids always have a low pH.
B).Strong acids always have a high pH.
C).Weak acids always partially dissociate.
D).Weak acids always fully dissociate
I believe the answer is B). Is this correct?
I read in my text that A high PH means that it is basic. So does this mean it the correct answer is A).?
thank you Ms. Sue, i appreciate it.
You're welcome, Kiley.
I took a test using the same reasoning, and got it wrong. I'm not sure what part of this is wrong but it is
A is not the correct answer
Weak acids always partially dissociate.
No, the correct answer is C). "Weak acids always partially dissociate."
To understand why this is the correct rewording, let's first clarify some concepts. pH is a measure of the acidity or basicity of a solution. It is expressed on a scale ranging from 0 to 14, where lower values indicate acidity, higher values indicate basicity, and a pH of 7 is considered neutral.
A strong acid is an acid that fully dissociates in water, meaning that it completely breaks apart into its constituent ions. Strong acids have a low pH because their dissociated ions contribute to the high concentration of hydrogen ions (H+) in the solution, making it acidic.
On the other hand, weak acids only partially dissociate in water, meaning that they do not completely break apart into ions. As a result, weak acids have a pH value that is typically greater than 7. Therefore, the reworded statement "Weak acids always partially dissociate" accurately reflects the behavior of weak acids and how it relates to pH.
No.
