EVERYDAY SCIENCE

Detailed explanation-1: -The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Detailed explanation-2: -The lower the number (0-7), the more acidic it’s considered. And the higher the number (7 to 14), the more basic it is. The pH scale may seem small, but each whole number represents a ten-fold leap in concentration of either H ions or OH ions. For example, rain is slightly acidic with a pH that measures about six.

Detailed explanation-3: -The scale has values ranging from zero (the most acidic) to 14 (the most basic).

Detailed explanation-4: -A pH less than 7 indicates an acidic solution while a pH of more than 7 indicates a basic solution. A pH close to 1 indicates a very strong acid while a pH just below 7 indicates the presence of a weak acid. Strong bases on the other hand have a pH close to 14 while weak bases have a pH just above 7.

Detailed explanation-5: -As the pH level increases, so does the alkaline. In other words, anything that has a pH level above 7 means the substance is alkaline. As a substance lowers in pH levels from a neutral 7 to anything below, it indicates an increase in acidity. A substance becomes increasingly more acidic as their pH levels decrease.
