We must remember that pH is defined as the -log[H+]. Therefore, 7.22=-log[H+]. By algebraic rearrangement, we get:
-7.22=log[H+]
10-7.22=[H+]
6.03x10-8=[H+]
We can check our answer by plugging it into the equation for pH.
-log(6.03x10-8)=pH=7.22

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.
What is the pH if the concentration of H plus ions is 4.5 times 10 to the -8?
if the pH is 4.7, the H+ concentration is 2 x 10-5
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
What is the pH of a soultion that has a h plus concentration of 0.001m?
pH = -log10[H+] = -log10(0.001 mol/L )= -log10(10-3)= 3
What is the difference between a pH of 6 and a pH of 8 in H plus concentration terms?
The difference between a pH of 7 and a pH of 8 are as follows:A pH of 7 means the concentration of [H+] is 10-7.A pH of 8 means the concentration of [H+] is 10-8.Therefore, a substance with a pH of 8 has 1/10th the concentration of hydrogen ions that a substance with a pH of 7.
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.
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 is the measure of acidity which is derived from the concentration of H plus?
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 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
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 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 changes shows a tenfold increase in concentration of H plus ions?
its pH 2 ---> pH 1
If the H plus is 0.0020 M the concentration of OH- is?
pH= -log[H+] pH + pOH = 14 pOH = 14 - pH pOH= -log[OH], so the antilog of -pOH will give you the OH concentration.
What is the pH if the concentration of H plus ions is 4.5 times 10 to the -8?
if the pH is 4.7, the H+ concentration is 2 x 10-5
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
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
