Question
An acid
- Is a substance that releases H+ ions when dissolved in water
- Is a substance that does not release any ions when dissolved in water
- Is a substance that releases OH- when dissolved in water
- Releases an equal amount of OH- and H+ ions when dissolved in water
Hint:
Acid has higher H+ concentration.
The correct answer is: Is a substance that releases H+ ions when dissolved in water
- Acid has higher H+ concentration and pH ranges from 0-6.
- According to Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H + ); that is, an acid increases the concentration of H + ions in an aqueous solution.
- An acid is a substance that releases H+ ions when dissolved in water.
