Which solution has the greatest concentration of H plus ions vinegar 2.5 milk 6.5 water 7.0 bleach 12.5?
Bleach with a pH of 12.5 has the greatest concentration of H+ ions because the pH scale is logarithmic, meaning a higher pH value corresponds to a lower concentration of H+ ions. Therefore, bleach, with the highest pH value, has the lowest concentration of H+ ions.
What happends to the OH- as the H plus increases?
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant
What does the direction of H plus diffusion across a membrane depend on?
Concentration. It will generally flow from an area of high concentration to an area of low concentration.
What is a measure of the H plus concentration in a solution?
pH is defined as -log[H+]. This means that if one knows the concentration of hydrogen ion in solution, the pH is simply the negative logarithm (base 10) of that. Similarly, one can find the pOH simply by substituting the concentration of OH- for the concentration of H+ in the aforementioned formula.
Which substances increase the H concentration in a solution?
H plus ion concentration can be decreased by adding base to the solution. The reduction can also be done by accepting hydrogen ions.

What would happen if there were H plus ion concentration difference when the channel opened?
H plus ions would not flow
How does the concentration gradient of H plus ions help make ATP?
High concentration of H+ ion in the intermembrane lead to the movement of H+ ions into the inner membrane
Do vinegar have a high H plus concentration?
Vinegar is an acid. But it is weak
How many times does the concentration of H plus increase or decrease when pH drops from 7 to 5?
When the pH drops from 7 to 5 the H plus concentration increases by 100 times. ie:for every drop back of pH by 1 unit the H plus concentration increases by 10 times.
What does the direction of H plus diffusion across a membrane depend on?
Concentration. It will generally flow from an area of high concentration to an area of low concentration.
If you add hydrochloric acid to water what effect would it have on the H plus concentration on the pH?
Adding hydrochloric acid to water would increase the concentration of H+ ions, leading to a decrease in pH. Hydrochloric acid dissociates in water to form more H+ ions, making the solution more acidic.
If an acid is added to a solution does the H plus concentration increase or decrease?
It increases.
What changes shows a tenfold increase in concentration of H plus ions?
10
What change shows a tenfold increase the concentration of h plus ions?
When pH value is decreased 1.0 unit, the H+ concentration is tenfolded, because -log(10.[H+]) = pH + 1.0
What is a measure of the H plus concentration in a solution?
pH is defined as -log[H+]. This means that if one knows the concentration of hydrogen ion in solution, the pH is simply the negative logarithm (base 10) of that. Similarly, one can find the pOH simply by substituting the concentration of OH- for the concentration of H+ in the aforementioned formula.
