Pure water has a pH of 7.0 which is the center of the pH scale.
The reason for a pH scale it to tell how basic or acidic a substance, or substance byproduct is.
Water is considered a pure substance because its pH is 7, which is right in the middle of the scale from 0-14.
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
Bases are anything above a 7 on the pH scale. A substance with a pH of 7 is considered neutral.
Water is the middle of the scale, with a pH of 7.
The pH scale measures how acidic or basic a substance is.
a pH scale.
The pH scale ranges from 0-14. From 0-6, the substance is acidic. A value of 7 means the substance is neutral. From 8-14, the substance is basic.
A pH of 11 is 1000x more alkaline than a pH of 8. The pH scale is a logarithmic scale. This means that in a pH scale, a change of one whole number represents a tenfold change in the pH. So a pH of 8 is 10x more alkaline than a pH of 7.
Somewhat acidic since 7 is the neutral point on the pH scale.
For example a pH=4-5.
The pH scale is used to measure how acidic or basic a substance is.
