A pH of 9 is considered basic on the pH scale, meaning it has a higher concentration of hydroxide ions compared to hydrogen ions. It is less acidic than neutral (pH 7) and falls in the range of alkaline substances.

How much stronger is pH 9 than pH 4?

The difference in strength between pH 9 and pH 4 is significant. As pH is measured on a logarithmic scale, each whole number change represents a 10-fold difference in acidity or basicity. In this case, pH 9 is 100,000 times stronger in basicity compared to pH 4.

What natural occurring pH 9?

This is a basic pH.


Is pH 9 more acidic than pH 4?

No, pH 9 is actually more basic (alkaline) than pH 4. The pH scale is logarithmic, so each unit is 10 times more acidic or basic than the unit next to it. pH 4 is more acidic than pH 9.


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

A pH of 5 is ................. as acidic as a pH of 9?

7 is neutral below 7 is acidic above 7 is basic therefore a pH of 5 is more acidic as a pH of 9


How much more acid is a solution of pH 6 from a solution oh pH 9?

A solution with a pH of 6 is ten times more acidic than a solution with a pH of 7, and a solution with a pH of 9 is ten times less acidic than a solution with a pH of 8. Therefore, the difference between pH 6 and pH 9 is three pH units, indicating that the pH 6 solution is 1,000 times more acidic than the pH 9 solution. This is because each pH unit represents a tenfold change in hydrogen ion concentration.


How does a solution with a pH of 6 compare to a solution with a pH of 9?

A solution with a pH of 6 is more acidic than a solution with a pH of 9. The pH scale ranges from 0 to 14, with lower values indicating higher acidity. Each whole number change in pH represents a tenfold difference in acidity or basicity.


Which solutions has a greater concentration of hydroxide ions a solution of pH 3 or a solution of pH 9?

A solution with a pH of 9 has a greater concentration of hydroxide ions than a solution with a pH of 3. The pH scale is a logarithmic scale, with each unit representing a tenfold difference in hydrogen ion concentration. Therefore, a solution with a pH of 9 has a concentration of hydroxide ions 1,000 times greater than a solution with a pH of 3.
