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.

Ostrovityanka [42]

The movement of food through the esophagus  is called peristalsis.

<h3>What is the buccal cavity?</h3>

The mouth is what we generally call the buccal cavity. It is an opening that contains the teeth and the tongue. The tongue plays the important role of serving as the organ of taste while the teeth serves to marsh food. It is the white strong structure that occurs in the mouth that enables is to masticate our food. Also in the mouth we have the salivary gland which plays the role of secreting the saliva and we know that the saliva contains from enzymes that makes it possible for the digestion of food to commence at the moth. It the follows that the buccal cavity is made up of the teeth, tongue and salivary glands.

Food moves into the stomach via the esophagus. Thus movement is slow and is aided by the muscles that line the gastro intestinal tract. As such, movement of food through the esophagus  is called peristalsis.
