The pH is the negative log of the concentration of hydronium ions. (pH=-log [H3O+]) If the pH is high, the substance is basic. If it is low the substance is acidic. When the pH is exactly 7 the substance is neutral.
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.
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
A low pH indicates that a substance is acidic.
The lowest pH level that can be measured in a substance is 0.
If a substance has a PH of 11 then the substance is basic.
The substance with the highest pH is liquid ammonia, which has a pH of about 11.6.
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.
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
The pH is determined with a pH-meter.
The reason for a pH scale it to tell how basic or acidic a substance, or substance byproduct is.
A low pH indicates that a substance is acidic.
The lowest pH level that can be measured in a substance is 0.
If a substance has a PH of 11 then the substance is basic.
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.
If the substance is in liquid form, the pH may be determined by litmus paper.
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.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
