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.
If a substance has a PH of 11 then the substance is basic.
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
Classify a substance that has negative pH value. Foods that have acids in them is a substance hat have pH.
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
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 pH of a substance can be found by using a litmus indicator.
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.
Dip an indicator into the substance and compare the colour to the chart.
pH is the measure of the levels of acid or base in a substance. Increasing the amount of a substance will not change the pH so long as the existing substance and the added substance are chemically the same.
pH ranges from 0 - 14. Ph of 0 - 6 are acidic and will turn litmus paper 'red. pH = 7 is neutral ( water) pH of 8 - 14 is alkaline and will turn litmus paper 'blue'.
PH scale is a scale that shows the substance is PH ....... Example: The substance is PH 7, so it is neutral The substance is PH 3, so it is acid The substance is PH 10, so it is alkali
