Difference between pH of 4 and pH of 10?
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.
Is a substance with a pH of 14 a strong base?
The pH is the cologarithm of the activity of hydrogen ion in solutions; pH 14 is the pH of a strong base.
What does it mean when a substance has a low pH?
When a substance has a low pH, it means that it is acidic. pH is a measure of how acidic or basic a substance is on a scale of 0 to 14, with lower numbers indicating higher acidity.
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.
The ph of a substance can be determined by using a device called what?
If the substance is in liquid form, the pH may be determined by litmus paper.
What does a pH number between 7-14 tells you about the substance?
it means its a basse i thinkk
What is the acidity or alkalinity of a substance called?
The acidity or alkalinity of a substance is called its pH level. pH measures the concentration of hydrogen ions in a solution, ranging from 0 (most acidic) to 14 (most alkaline), with 7 considered neutral. A substance with a pH less than 7 is acidic, while a substance with a pH greater than 7 is alkaline.
On the pH scale any substance with a value between 0 and 6 is considered?
An acid. pH of 7 is considered neutral & pH of 8-14 is considered basic.
What is pH of 7 called?
It is called a neutral substance. It is not acid or base. It is neutral between them.

Is a substance with a pH of 14 a strong base?
The pH is the cologarithm of the activity of hydrogen ion in solutions; pH 14 is the pH of a strong base.
What is a substance with a pH of 6?
The pH scale runs from 0 to 14. Pure water has a pH of 7, the half-way point of the pH scale. A pH between 0 and 7 indicates that a solution is acidic, and the lower the pH, the higher the acidity. A pH between 7 and 14 indicates that a substance is alkaline, and the higher the pH, the higher the strength of the alkali.
What is the sum of the pH and pOH in a substance.?
The sum is 14 at room temperature.
What does it mean when a substance has a low pH?
When a substance has a low pH, it means that it is acidic. pH is a measure of how acidic or basic a substance is on a scale of 0 to 14, with lower numbers indicating higher acidity.
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 is it called when a substance changes color in response to pH?
This is a pH indicator.
The ph of a substance can be determined by using a device called what?
If the substance is in liquid form, the pH may be determined by litmus paper.
