Examine the false statement.
Weak acids always have a high pH.
Select the rewording that makes the statement true.
Strong acids always have a low pH.
Weak acids always fully dissociate.
Weak acids always partially dissociate.
Strong acids always have a high pH.
is it 2?
No, the correct rewording that makes the statement true is option 3: Weak acids always partially dissociate.
To examine the false statement, we need to understand the properties of weak acids and pH. A weak acid is an acid that only partially dissociates in water, meaning it does not fully break apart into ions. On the other hand, a strong acid fully dissociates in water, breaking apart completely into ions.
pH is a measure of the acidity or basicity of a solution. It is determined by the concentration of hydrogen ions (H+) in the solution. The pH scale ranges from 0 to 14, where pH values below 7 indicate acidity, pH values above 7 indicate basicity, and a pH of 7 is considered neutral.
The false statement in the original question states that weak acids always have a high pH, which is incorrect. This statement fails to acknowledge that weak acids only partially dissociate, resulting in a lower concentration of hydrogen ions. Consequently, the pH of a weak acid solution will be below 7, indicating acidity.
The correct rewording to make the statement true is option 3: Weak acids always partially dissociate.
