What is a pH scale and how is it arranged?

The pH scale is a measure of acidity or alkalinity of a solution, ranging from 0 to 14. A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline. The scale is logarithmic, meaning each whole number change represents a tenfold change in acidity or alkalinity.

What is used to measure the alkalinity or acidity of a substance?

On the pH scale. The pH scale goes from 1 to 14, 1 being very acidic, 7 being neutral and 14 being very alkaline (basic). The pH scale is (loosely speaking) a measure of the concentration of free-floating hydrogen ions in a solution.


Why can't you use a pH chart with litmus paper?

Why is the pH scale significant?

The pH scale shows the relative acidity (H+ ions) and basicity (OH- ions) of a sample. A pH of &lt;7.0 is acidic; a 7.0 pH is neutral and, one with a pH &gt;7.0 is basic.


Which pH values indicates a slightly acidic solution?

Is lemon juice an acid or a base or neutral?

Foods such as orange juice and lemon juice are acidic in their natural state but turn alkaline after they have been metabolized in the body. As such, for dietetic purposes they are usually considered to be alkaline forming foods despite being acidic prior to consumption. Most fruits are alkaline except a few that include cranberries, plums and prunes. These fruits are classified as acidic because they contain acids the body can't metabolize.

How do you indicate that a solution is a alkaline solution or a base?

By using a universal pH indicator. If the pH indicator turns from red to blue, it will shows that it is a alkaline solution or a base, if the pH indicator turns from blue to red, it shows that it is an acidic solution. Hope its use full info for you&gt;&gt;&gt;:)d
