How does the concentration of H affect the number on the pH scale?
The meaning of a higher H+ concentration is a low pH.
Is a single unit change on the pH scale equivalent to 1 percent change in hydrogen ion concentration?
No, a single unit change on the pH scale represents a tenfold change in hydrogen ion concentration, not a 1 percent change. For example, moving from a pH of 5 to a pH of 4 means the hydrogen ion concentration increases by a factor of 10.
A substance with a pH of 11 is what times more what than a substance with a pH of 8?
A pH of 11 is 1000x more alkaline than a pH of 8. The pH scale is a logarithmic scale. This means that in a pH scale, a change of one whole number represents a tenfold change in the pH. So a pH of 8 is 10x more alkaline than a pH of 7.
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.
Is drinking pop a physical change?
Drinking pop can change your PH scale if you drink a lot of it
Which change shows a tenfold increase in concentration h ions?
pH 2 -> pH 1
What is the increase in acidity associated with a decrease of one unit on the pH scale?
A decrease of one unit on the pH scale represents a tenfold increase in acidity. This is because the pH scale is logarithmic, meaning each whole number change reflects a tenfold change in hydrogen ion concentration. For example, a solution with a pH of 5 is ten times more acidic than one with a pH of 6.
What are four characteristics of the pH scale?
The pH scale measures the acidity or basicity of a solution on a scale of 0 to 14. A pH of 7 is considered neutral, with lower values indicating acidity and higher values indicating basicity. Each unit change in pH represents a tenfold change in the concentration of hydrogen ions in the solution. The pH scale is logarithmic, meaning a difference of one unit corresponds to a tenfold difference in hydrogen ion concentration.
How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
What scale is used to determine pH?
the pH scale
What scale describes the acidity of a solution as a number?
the pH
Which change shows a tenfold increases in concentration of h ions?
pH 2 -> pH 1
