The reference electrode in a pH meter probe can lose ions through interactions with the surrounding environment. A) True B) False
Understand the Problem
The question is asking whether the statement regarding the reference electrode in a pH meter probe losing ions through interactions with its environment is true or false.
Answer
True
The final answer is True.
Answer for screen readers
The final answer is True.
More Information
The reference electrode in a pH meter can indeed lose ions through interactions with the surrounding environment. This occurs when ions such as lead, iron, chrome, and others contaminate the electrode or interact with it, altering its stable electrochemical potential.
Tips
A common mistake is to store electrodes in distilled or deionized water which can cause ion loss; it's better to store them in a suitable storage solution.
