The H in pH stands for hydrogen.
If the pH is 5, then the concentration of hydrogen ions is 10-5 moles per liter.

A solution of HCl is 0.01 m what are the h plus and pH of this soluton?
The concentration of H+ [H+] = 0.01 m/l by definition pH = -(log10 (0.01)) therefore pH = 2
What is the PH of a solution with and H plus of 3.7x10-6?
pH = -log[H+] = -log(3.7 x 10-6) = 5.43
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.
If you add hydrochloric acid to water what effect would it have on the H plus concentration on the pH?
Hydrochloric acid is HCl. It is a H plus (H^+) donor, and so adding it to water will INCREASE the H^+ concentration. Increasing the H^+ concentration results in a DECREASE in pH.
What is the measure of acidity which is derived from the concentration of H plus?
pH
What is the pH of solution with H plus 2.310?
pH = -log [H+], so if the [H+] is 2.310 M, the pH = -0.3636
What effect will decreasing the H plus of a solution have on pH?
It will increase the pH
Do buffers release H plus ions when pH increases?
No they release Negative H ions when pH increases
A solution of HCl is 0.01 m what are the h plus and pH of this soluton?
The concentration of H+ [H+] = 0.01 m/l by definition pH = -(log10 (0.01)) therefore pH = 2
How does an increase in the cocentration of H plus affect the number on the pH scale?
As the concentration of H+ increases, the value of pH decreases simultaneously.
What is the PH of a solution with and H plus of 3.7x10-6?
pH = -log[H+] = -log(3.7 x 10-6) = 5.43
What is the pH of a solution with a H plus equals 10 -8?
2
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.
Associate pH numbers to H plus concentration?
The pH is the co-logarithm of the activity of the dissolved ions H+ in a solution. The formula is (a is the activity):pH = - log10 aH
If you add hydrochloric acid to water what effect would it have on the H plus concentration on the pH?
Hydrochloric acid is HCl. It is a H plus (H^+) donor, and so adding it to water will INCREASE the H^+ concentration. Increasing the H^+ concentration results in a DECREASE in pH.
What is the pH for a solution that has h plus equals 3.6 x 10 -9 M?
pH means -log10(H+concentration) so pH of a H+ concentration 3.6x10-9 is: pH = -log10(3.6x10-9) ≈ 8.4
What is the measure of acidity which is derived from the concentration of H plus?
pH
