The pH scale ranges from 0-14 pH. A substance that has a pH of 7 is considered to be "neutral," like pure water. A substance that has a pH less than 7 is said to be acidic, and a substance that has a pH greater than 7 is said to be basic. Therefore, the difference between those two pH levels is that the 4 pH substance is more acidic and the 10 pH substance is more basic. The more basic or acidic, the more caustic and/or corrosive the substance will be.
The answer is 2 ^^the above is TOTALLY wrong! the difference between say pH 2 and pH 3 is a difference of 10...im not sure if the difference of pH 2 and pH 4 is 100 or 20 because im not sure if you add the 10's or if you multiply them...but the answer is deffiently either 100 or 20...sorry i didnt help much :/
The difference in hydrogen ion concentration between solutions with pH 4 and pH 5 is tenfold. A solution with pH 4 has 10 times more hydrogen ions (H+) compared to a solution with pH 5. This is because the pH scale is logarithmic, with each unit change representing a 10-fold change in hydrogen ion concentration.
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.
The main difference between pH 4 and pH 6 is the concentration of hydrogen ions in the solution. A pH of 4 indicates a higher concentration of hydrogen ions compared to a pH of 6, which means the solution with pH 4 is more acidic than the solution with pH 6.
Each number on the pH scale represents a 10-fold difference from the number before or after it, so that pH5 is 10x more acidic than pH6 which is 10x more acidic than pH7. Since the difference between 9 and 5 is 4, the acidity would be 4 tens multiplied together: 10 x 10 x 10 x 10 (or 104), BUT.... the question asks for the difference in acidity at pH9 compared to pH5. pH9 is weaker, so we use the inverse. pH9 is only 1/104 as acidic as pH5.

The difference is 10
Each number on the pH scale represents a 10-fold difference from the number before or after it, so that pH5 is 10x more acidic than pH6 which is 10x more acidic than pH7. Since the difference between 9 and 5 is 4, the acidity would be 4 tens multiplied together: 10 x 10 x 10 x 10 (or 104), BUT.... the question asks for the difference in acidity at pH9 compared to pH5. pH9 is weaker, so we use the inverse. pH9 is only 1/104 as acidic as pH5.
The pOH is 6,4.
-log(10^-4 M) = 4 14 - 4 = 10 pH
Each pH unit on the pH scale represents a tenfold change in the hydrogen ion concentration. For example, a pH of 4 has 10 times more hydrogen ions than a pH of 5, and 100 times more hydrogen ions than a pH of 6.
A substance with a pH of 2 is 1000 times more acidic than a substance with a pH of 6. This is because each unit change on the pH scale represents a 10-fold change in acidity. So, the difference in pH of 4 units means a 10^4 or 10000-fold difference in acidity.
10^4 as each pH is equal to 10 times difference so an acid of pH 7 would be 104 weaker than an acid of pH 3
The difference between 4 degrees and -10 degrees is 14 degrees. When subtracting a negative number, it is equivalent to adding the positive value. Therefore, 4 - (-10) = 4 + 10 = 14.
