Verified
A solution that has a high concentration of hydroxide (OH-) ions
A) has a low pH.
B) has a high concentration of hydrogen (H+) ions too.
C) is a basic (alkaline) solution.
D) is a neutral solution.
E) is an acidic solution.
Hydroxide ions
Negatively charged ions made up of one oxygen and one hydrogen atom, symbolized as OH-.
Alkaline Solution
A solution with a pH value greater than 7, indicating it has fewer hydrogen ions than pure water and is commonly referred to as basic.
Basic Solution
A solution that has a pH greater than 7, indicating it has a higher concentration of hydroxide ions than hydrogen ions.
- Understand the concept of pH and its scale, including the role of hydrogen (H+) and hydroxide (OH-) ions in determining acidity or basicity.

Final Answer :
C
Explanation :
A high concentration of hydroxide ions indicates a basic or alkaline solution, as hydroxide ions have a pH above 7. Acidic solutions have a high concentration of hydrogen ions (H+) and a low pH. Neutral solutions have an equal concentration of hydrogen and hydroxide ions and a pH of 7.
