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

Is the pH of a solution of the concentration of H plus in the solution right?

Yes, the pH of a solution is a measure of the concentration of hydrogen ions (H+) in the solution. pH is defined as the negative logarithm of the hydrogen ion concentration.


PH -logH plus where H plus is the hydrogen ion concentration measured in miles per liter. What is the pH of a solution whose concentration of hydrogen ions is 6.98 10-7 moles per liter?

The pH is 6,15.


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.


Which changes shows a tenfold increase in concentration of H plus ions?

its pH 2 ---> pH 1


The sum of pH plus pOH?

The sum of pH and pOH is always equal to 14 in a neutral solution at 25°C. This is because pH is a measure of the concentration of H+ ions in a solution while pOH is a measure of the concentration of OH- ions. In a neutral solution, the concentration of H+ ions is equal to the concentration of OH- ions, resulting in a sum of 14.


Series of numbers that indicates the concentration of hydrogen ions in solution?

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


Which answer is a true statement about pH valuesPure water has a pH of 0 pH is important in life mainly because it affects the cohesion of water A high pH corresponds to a high H plus concentration?

Pure water has a pH=7.High pH correspond to high OH- concentration.


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.


What is the pH of an aqueous solution if the concentration of H plus equals 0.00097?

pH s calculated as the negative log10 of the hydrogen ion concentration. So log10 of 0.000724 = -3.14 so pH= 3.14


Ph solution by 2 numbers change in hydrogen ions by?

The pH scale is logarithmic, meaning each change of one unit represents a tenfold change in hydrogen ion concentration. For example, a change of 2 in pH corresponds to a 100-fold difference in hydrogen ion concentration. An increase in pH by 2 indicates a decrease in hydrogen ion concentration, while a decrease in pH by 2 indicates an increase in hydrogen ion concentration.


What effect will decreasing the H plus of a solution have on pH?

Decreasing the concentration of H+ ions will raise the pH of the solution because pH is a measure of the hydrogen ion concentration. As H+ ions decrease, the solution becomes more basic and the pH value increases.
