Which of the following best represents the relationship of the concentration of hydrogen ions between water, vinegar, and ammoni
aalyn [17]

Answer: The second image best represents the relationship of the concentration of hydrogen ions between water, vinegar and ammonia.

Explanation: pH is the measure of alkalinity and acidity of a substance in a logarithmic scale.

Mathematically,

pH=-\log[H^+]

The solutions which lie in the pH range of 0 - 6.9 are considered as acidic solutions and they have more hydrogen ion concentration.

The solution which has a pH value of 7 is considered as a neutral solution and this solution has same hydrogen and hydroxide ion concentration.

The solutions which lie in the pH range of 7.1 - 14 are considered as basic solutions and they have less hydrogen ion concentration.

  • For vinegar, the hydrogen ion concentration is very high.
  • For water, the hydrogen ion concentration will be equal to the hydroxide ion concentration.
  • For ammonia, the hydrogen ion concentration is very less.
