Gold nanorods can be grown from a solution which contains more hydroxide ions than hydrogen ions.
Understand the Problem
The question is asking to complete a sentence by choosing the correct words to indicate the relationship between hydroxide and hydrogen ions in a solution used for growing gold nanorods. It requires knowledge of chemistry concepts relating to these ions.
Answer
More hydroxide ions than hydrogen ions.
The solution should contain more hydroxide ions than hydrogen ions.
Answer for screen readers
The solution should contain more hydroxide ions than hydrogen ions.
More Information
The growth environment for gold nanorods usually requires a basic solution, which is characterized by a higher concentration of hydroxide ions.
Tips
Ensure that the concept of basic solutions (high OH- concentration) is understood, as it is central to this context.
