Question
Acidic and basic solutions in water conduct electricity because they produce ______ and hydroxide ion, respectively.
The correct answer is
hydrogen
The correct answer is Hydrogen.
Key Points
- Acidic and alkaline solutions in water conduct electricity because they produce hydrogen and hydroxide ions, respectively.
- Acids and bases exhibit their conducting properties only when they are in an aqueous solution where they can completely ionize in water.
- According to the Arrhenius concept, acids are substances that produce hydrogen ions (H+) when dissolved in water.
- Bases produce hydroxide ions (OH-) when dissolved in water.
- These ions, when in water, act as charge carriers and can therefore conduct electricity.
- The pH level is a measure of the number of hydrogen ions in a solution.
- The lower a solution or compound is on the pH scale, the higher the concentration of hydrogen ions will be.
