The pH of pure water is 7
If a substance has a PH of 11 then the substance is basic.
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.
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
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
Classify a substance that has negative pH value. Foods that have acids in them is a substance hat have pH.
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.
Dip an indicator into the substance and compare the colour to the chart.
