A substance has a pH of 7. Which of the following descriptions matches this pH?
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.
What is the pH of a substance?
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.
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
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).
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.

At what pH is a substance an acid or a base?
A substance is considered an acid if the pH is less than 7, indicating a high concentration of hydrogen ions. A substance is considered a base if the pH is greater than 7, indicating a low concentration of hydrogen ions and a higher concentration of hydroxide ions.
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).
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
What Substance that has a pH higher than 7?
Substances with a pH higher than 7 are considered basic or alkaline. An example of a substance with a pH higher than 7 is baking soda (sodium bicarbonate), which typically has a pH of around 8.3 when dissolved in water.
