A substance with a pH of 7 is neutral, meaning it is neither acidic nor basic. Water has a pH of 7 at room temperature, so the substance could be water.
pH is a measure of the acidity or basicity of a substance on a scale from 0 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic. pH is determined by the concentration of hydrogen ions in the substance.
A substance with a neutral pH has a pH of 7, indicating that it is neither acidic nor basic. Neutral pH means that the concentration of hydrogen ions is equal to the concentration of hydroxide ions in the substance. Water is an example of a substance with a neutral pH.
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
A substance with a pH below 7 is an acid. Acids have a pH below 7, while substances with a pH above 7 are alkalis (bases).
