pH
for every value of 1 integer in either direction, there is a difference of 1 magnitude of acidity or basicity. since pH 11 and 9 are considered bases, the weakest base is pH9. 11-9 = 2, therefore there is an order of 2 magnitudes greater basicity with a pH of 11 over pH 9, one hunder times as basic
Neutral is the term that is used to describe a solution with a pH of 7.Specifically, the pH level is an indication of acidity, neutrality or alkalinity. Between 0 and 7 the readings indicate acidity. Between 7 and 14 is the alkaline range.
A P.H Scale is most commonly used to measure this stuff. 0-6 are the acids, where zero is the most acidic and 6 is the weakest acids. 7 is neutral and 8-14 are the bases. 14 is the most basic and 8 is the weakest base.
Universal Indicator is used to test for the acidity of a solution, because the universal indicator has a wider range of pH that it can explain why a substance is acidic or basic.
The pH measure the acidity or basicity of a solution; the range is 1-14. Acidity is under pH=7, basicity is over pH=7, pH=7 is neutral.

The acidity range is a part of the pH scale.
An acidic solution will have a pOH ranging from 7 to 14

Phenolphthalein changes from colorless to pink in the range of pH 8.2 - 10. If toothpaste has a pH that is below this range, phenolphthalein will not indicate the basicity. if the pH is higher, which I believe it is in most (some) toothpastes, then phenolphthalein can be used, because it will turn from colorless to pink.
Universal Indicator is used to test for the acidity of a solution, because the universal indicator has a wider range of pH that it can explain why a substance is acidic or basic.
A: Hydrochloric acid (HCl) is a strong acid that dissociates completely in water, releasing hydrogen ions (H⁺). The pH scale is a measure of the acidity or basicity of a solution, ranging from 0 to 14, with 7 being neutral. Solutions with a pH less than 7 are considered acidic, while those with a pH greater than 7 are considered basic or alkaline. Hydrochloric acid is highly acidic, and when dissolved in water, it contributes a large number of hydrogen ions, resulting in a low pH. The pH of hydrochloric acid typically falls in the range of 0 to 1, indicating a strong acidity. It's important to note that the pH scale is logarithmic, meaning that each unit change represents a tenfold difference in acidity or basicity. Therefore, a solution with a pH of 1 is ten times more acidic than a solution with a pH of 2. In summary, hydrochloric acid is a strong acid with a low pH on the pH scale, reflecting its highly acidic nature when dissolved in water.
pH scale...... for acidity it is 0-6.9, neutral is 7.0, Basic is 7.1-14.0
