Considered to be a strong base since a pH of 11 indicates alkalinity. This substance would have a high concentration of hydroxide ions and a low concentration of hydrogen ions.
A substance with a negative pH value indicates a strong acid with high concentration of hydrogen ions (H+). The lower the pH value, the higher the acidity of the substance. Negative pH values are possible for highly concentrated acids, like hydrochloric acid.
A strong acid has a pH value close to 0, a strong base has a pH value close to 14, and a neutral substance has a pH value of 7.
The most acidic pH among the options given is pH 2. pH values below 7 indicate acidity, with lower values being more acidic.
The pH value of an acid is below 7. It ranges from 0 to 6.9, indicating a high concentration of hydrogen ions in the substance.
Considered to be a strong base since a pH of 11 indicates alkalinity. This substance would have a high concentration of hydroxide ions and a low concentration of hydrogen ions.
A substance with a negative pH value indicates a strong acid with high concentration of hydrogen ions (H+). The lower the pH value, the higher the acidity of the substance. Negative pH values are possible for highly concentrated acids, like hydrochloric acid.
It would take more drops of antacid to neutralize a substance with a pH of 13 compared to a substance with a pH of 11. This is because a substance with a pH of 13 is more basic and therefore requires more acidity to neutralize it.
A strong acid has a pH value close to 0, a strong base has a pH value close to 14, and a neutral substance has a pH value of 7.
The most acidic pH among the options given is pH 2. pH values below 7 indicate acidity, with lower values being more acidic.
The pH value of an acid is below 7. It ranges from 0 to 6.9, indicating a high concentration of hydrogen ions in the substance.
A pH value of 5 indicates that the substance is slightly acidic. This pH level suggests that the substance has a higher concentration of hydrogen ions than a neutral substance (pH 7) but lower than stronger acids. Examples of substances with a pH of 5 include coffee and tomatoes.
A substance with a pH of 11 is 1000 times more basic than a substance with a pH of 8. This is because the pH scale is logarithmic, with each unit representing a tenfold difference in hydrogen ion concentration.
To determine the pH of a substance using the pH method, you will need a pH meter or pH strips. For a pH meter, simply immerse the electrode into the substance and wait for the reading to stabilize. For pH strips, dip the strip into the substance and compare the color change to the provided chart to determine the pH value.
11 to 14
A pH value of 7 is considered neutral on the pH scale. This means that the substance is neither acidic nor basic.
A substance with a pH value of 2 would be considered very acidic, as pH values below 7 indicate acidity.
