How does a solution of pH 7 compare to a solution of pH 10?
A pH 7 solution is neutral, indicating a balance of acidic and basic components, while a pH 10 solution is basic, meaning it has a higher concentration of hydroxide ions. The pH scale is logarithmic, so a pH 10 solution is 1000 times more basic than a pH 7 solution.
What sentence correctly describes a solution with a pH lower that the pH of distilled water?
A solution with a pH lower than that of distilled water is considered acidic.
What property of a solution is described by its pH?
The pH of a solution describes its acidity or basicity. Solutions with a pH below 7 are acidic, while solutions with a pH above 7 are basic. A pH of 7 indicates a neutral solution.
If a solution has a hydrogen ion concentration of 10-5M what is its pH?
The pH of a solution is defined as -log10[H+]. Thus a solution with a hydrogen ion concentration of 10-5M has a pH of 5. [H+] = 10-5 pH = -log[H+] pH = - log [10-5] pH = 5
What sentence correctly describes a solution with a pH lower than the pH of distilled water?
A solution with a pH lower than the pH of distilled water is acidic. The pH of distilled water is 7, so any solution with a pH below 7 is considered acidic.
What scale describes the acidity of a solution as a number?
the pH

What sentence correctly describes a solution with a pH lower than the pH of distilled water?
A solution with a pH lower than the pH of distilled water is acidic. The pH of distilled water is 7, so any solution with a pH below 7 is considered acidic.
If a solution has a pH of 10 that solution is?
...that solution is alkaline or basic.
What is the pH of a solution that has a hydronium ion concentration of 1.00 10 -10 M?
The pH of the solution is 10. The pH is calculated as the negative base 10 logarithm of the hydronium ion concentration. pH = -log[H3O+]. In this case, pH = -log(1.00 x 10^-10) = 10.
What is the pH of a solution with H 1.25 x 1010?
The pH of a solution with a concentration of H+ ions of 1.25 x 10^10 would be calculated as pH = -log[H+]. Therefore, pH = -log(1.25 x 10^10) ≈ 9.9. This solution would be basic.
What equation is used to calculate the pH of a solution?
pH = -log [H+(aq)]. In words, pH is the negative logarithm (to the base 10) of the hydrogen ion concentration.
How does a solution with a pH of 2 compare to a solution with a pH of 1?
A solution with a pH of 2 is less acidic than a solution with a pH of 1. The pH scale is logarithmic, so each unit change represents a tenfold difference in acidity. Therefore, a solution with a pH of 1 is 10 times more acidic than a solution with a pH of 2.
What would be the pH of a solution with a hydroxide ion OH- concentration of 10-4 M?
-log(10^-4 M) = 4 14 - 4 = 10 pH
