The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.
The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.
- The concentration of hydrogen ions is inversely related to its pH
- More hydrogen ions present, the lower the pH
- The fewer hydrogen ions, the higher the pH We know,
pH = -log(H+) then,
=> 5 = -log (H+)
=> H+ =
(for pH = 5)
=> pH = -log(H+)
=> 6 = -log (H+)
=> H+ =
(for pH = 6)
Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.

Answer:
The correct option is <u>C. The nervous system when the brain regulates the body's breathing and heart rate.</u>
Explanation:
The main function of the respiratory system is to exchange oxygen for carbon dioxide in the body.
The brain controls the rate at which the heart pumps blood. The pumping of the heart supplies oxygenated blood to other parts of the body. Hence, the rate at which heart pumps blood is very important to maintain homeostasis of the respiratory system.
The brain regulates the rate at which a person breathes. This rate is very important to breathe in the right amount of oxygen and to breathe out the right amount of carbon dioxide.
