What makes water “neutral “ (pH of 7)

Biology
1 answer:
Mandarinka [93]3 years ago
4 0

Answer:

Even in pure water ions tend to form due to random processes (producing some H+ and OH- ions). The amount of H+ that is made in pure water is about equal to a pH of 7. That's why 7 is neutral. ... In pure water near room temperature, the concentration of H+ is about 10-7 moles/liter, which gives a pH of 7.

kykrilka [37]

Answer: One H⁺ ion ie required in converting ATP and inorganic phosphate to ATP

Explanation:During oxidative phosphorylation, high energy electrons released by hydrogen carriers are shuttled through the electron transport chain. The released energy is used to translocate 3 H+ ions from the matrix, creating an proton motive force, which will cause 1 H+ ion to move down the electrochemical gradient and diffuse back into the matrix (chemiosmosis) which is facilitated by ATP synthase. As the H+ moves through the ATP synthase this triggers the molecular rotation of the enzyme, synthesizing ATP

What is the difference between a lake and a pond? a. A pond is smaller in size and does not have a temperature gradient. b. A po
Ksju [112]

Answer:

I think the answer is A.

Explanation:

Ponds and lakes are both inland bodies of freshwater that contain living creatures. Lakes are normally much deeper than ponds and have a larger surface area. ... All the water in a pond is in the photic zone, meaning ponds are shallow enough to allow sunlight to reach the bottom.

  The yearly process known as thermal stratification. A pond that is thermally stratified simply means that there is a noticeable temperature gradient as the water gets deeper. You may have noticed this in summer while swimming.
