A substance has a pH of 7. Which of the following descriptions matches this pH?
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
What is the pH of a substance?
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.
What does it mean for a substance to have a neutral pH?
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.
What scale is 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
At what pH is a substance an acid or a base?
The pH is measure from 1 to 14. so, from 1 to 6.9 the substance is acidic. and from 7.01 to 14 the substance is basic. 7 is neutral. The closer the substance is to 7 it is either basic or acidic. As the number is lower the substance is more acidic for example: pH 2.9 is more acidic than pH 4.8
What is the scale range of a neutral substance?
7 The pH of a neutral substance is 7. Anything higher than 7 is alkaline or basic, and anything lower than 7 is acidic.
Neutral substances have this pH?
Neutral substances have a pH of 7, which means they are neither acidic nor basic. Water is an example of a neutral substance with a pH of 7.
What is a substance that has a pH of more than 7.0.?
an example is baking soda, milk of magnesia, blood.

Is a substance with a pH below 7 an acid or an 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).
A substance has a pH of 7 what matches it?
A substance with a pH of 7 is considered neutral, meaning it is neither acidic nor basic. Pure water is the most common example of a substance with a pH of 7. At this pH level, the concentration of hydrogen ions (H⁺) is equal to the concentration of hydroxide ions (OH⁻). Other neutral substances can include certain saline solutions.
What is a neutral pH mean?
The pH scale ranges from 0 to 14 such that something with a pH of 0 is extremely acidic and something with a pH of 14 is extremely basic. A neutral pH is in the middle and has a pH of 7. An example of something with a pH of 7 is rain water.
How would you classify a substance with a pH of 7 below 7 and above 7?
a substance of pH of 7 is neutralbelow 7 is an acidabove a 7 is a base
