Bases have a pH > 7.0 BUT this merely describes the concentration of ions. Strong usually describes if all the substance ionizes, not how many ions are present.
EX. NaOH is a strong base, but the pH of a solution of NaOH can be anywhere from 7.1 to 14 depending on how much has been dissolved.

What scale is used to indicate whether something is acid or alkaline?
The pH scale is the widely used universal scale, (which measures the hydrogen ion concentration of solutions) to measure the acidity or alkalinity of chemical solutions. It should be mentioned that the pH value is dependent on the temperature.
What does the pH scasle indicate?
The pH scale measures the acidity or alkalinity of a solution, ranging from 0 to 14. A pH of 7 is considered neutral, while values below 7 indicate acidity and values above 7 indicate alkalinity. Each unit change on the scale represents a tenfold change in hydrogen ion concentration, meaning a solution with a pH of 6 is ten times more acidic than one with a pH of 7. The pH scale is essential in various fields, including chemistry, biology, and environmental science, as it affects chemical reactions and biological processes.
If a substance is found at the high end of the pH scale is it an acid or a base?
A substance found at the high end of the pH scale is a base. The pH scale ranges from 0 to 14, with values below 7 indicating acidity, 7 indicating neutrality, and values above 7 indicating basicity. Therefore, a high pH signifies that the substance has a higher concentration of hydroxide ions (OH⁻) compared to hydrogen ions (H⁺).
Is 7.7 acidic basic or neutral?
A pH of 7.7 is slightly basic. The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 indicate acidity, while values above 7 indicate alkalinity. Therefore, a pH of 7.7 is just above neutral, making it mildly basic.
What is pH value corresponds to acidic compounds?
The pH scale ranges from 0 to 14, with values below 7 indicating acidity. Acidic compounds typically have a pH value less than 7, with strong acids having pH values closer to 0. A pH of 7 is considered neutral, while values above 7 indicate alkalinity or basicity.
What is the scale used to indicate the strength of an acid or base called?
The scale used to indicate the strength of an acid or base is called the pH scale. It ranges from 0 to 14, with 7 being neutral, values below 7 indicating acidity, and values above 7 indicating alkalinity.
What is a pH range of a base?
A base typically has a pH range of 8 to 14. pH values above 7 indicate alkalinity, with higher values indicating stronger bases.
What is the pH indicator scale?
it indicate the acid and base of the scale
Is a base a acid on the pH scale?
No, a base is the opposite of an acid on the pH scale. Acids have pH values less than 7, while bases have pH values greater than 7. A neutral pH is 7.
Is a solution with a pH 6 an acid or a base?
A solution with a pH of 6 is considered acidic. pH values below 7 indicate acidity, while pH values above 7 indicate alkalinity.
Is a pH 4 a base or an acid?
pH = 4 is mildly acidic. The pH scale is [H = 1 strongly acidic pH = 4 mildly acidic pH = 7 neutral ( Water) pH = 9 mildly alkaline pH = 14 strongly alkaline.
What scale do chemists use to describe th relative strngth of an acid or base?
Chemists use the pH scale to describe the relative strength of an acid or base. Acids have pH values less than 7, while bases have pH values greater than 7. The lower the pH value, the stronger the acid, and the higher the pH value, the stronger the base.
What scale is used to indicate whether something is acid or alkaline?
The pH scale is the widely used universal scale, (which measures the hydrogen ion concentration of solutions) to measure the acidity or alkalinity of chemical solutions. It should be mentioned that the pH value is dependent on the temperature.
Does a pH of 12 indicate a strong or weak base?
A pH of 12 indicates a strong base. The pH scale ranges from 0 to 14, with values less than 7 indicating acidity, 7 being neutral, and values higher than 7 indicating alkalinity. A pH of 12 is considered highly alkaline or basic.
Measurement system used to indicate the concentration of hydrogen ions in solution?
pH scale is used to indicate the concentration of hydrogen ions in a solution. It is a measure of the acidity or alkalinity of a solution, with lower pH values indicating higher acidity and higher pH values indicating higher alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral.
What is pH mean?
pH is a measure of the acidity or basicity of a solution. It is quantified on a scale from 0 to 14, where values below 7 indicate acidity, 7 is neutral, and values above 7 indicate alkalinity.
Using the pH scale what numbers indicate an acid What numbers indicate a base?
pH numbers below 7 indicate an acid, with lower numbers indicating stronger acids. pH numbers above 7 indicate a base, with higher numbers indicating stronger bases.
