pH is the logarithm of a concentration (multiplied by -1). So you can in principle have any pH, such as -2, +18 etc.
No.
Any number that is greater than 14 or less than -14 will have an absolute value greater than 14. Mathematically expressed as if |n| > 14 then n > 14 or n < -14.
No it isn't.
14 is greater than -15
34 is greater than 14.
No.
Alkalines, or bases, have a pH greater than 7 (maximum is 14).
The pH range for alkali substances is typically between 7.1 and 14. Alkalis have pH values greater than 7, indicating their basic nature.
It would have to have a pH of greater than seven.
Acids do not have a pH greater than 7. When the pH is greater than 7, this makes it a base.
pH ranges from 0-14, 7 being neutral, under that acid, above base.
The pH of a basic solution is greater than 7. Basic solutions have a pH between 7.1 and 14. A pH value above 7 indicates a solution is basic or alkaline.
pH greater than 7.
Yes, bases have a pH greater than 7. They typically have pH values higher than 7 up to 14, indicating their alkaline nature.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
No, alkaline is not the same as pH. Alkaline refers to substances that have a pH greater than 7, while pH is a measure of the acidity or basicity of a substance on a scale from 0 to 14.
The pH scale. The pH scale goes from 0 to 14. Substances that have a pH of 7 are neutral, acids have a pH of less than 7, and bases have a pH of greater than 7.
