Answer: Substances that contains hydrogen ion or that has a pH value between 0 and 6 inclusive.
Explanation:
Chemical substances can either be acidic or basic based on their value on the pH meter. pH meter is an instrument used to determine the acidity and basicity of a chemical substance. On a pH scale, there are numbers from 0 to 14.
If the value on the pH falls between 0-6, then the substance is acidic otherwise it is basic.
Also, if the substance in question contains Hydrogen ion it can be said as been acidic
The [tex]\rm{H^{+\\} }[/tex] ions show the acidic nature of the substance on the other hand pH value is also useful to further find the acidity of any substance. pH ranges between 0 to 7 show acidity. Substances containing [tex]\rm{H^{+\\} }[/tex] ion tends to be acidic.
The acid substances contain [tex]\rm{H^{+\\} }[/tex] ions while basic substances contain [tex]\RM{OH}^{-}[/tex] ions further combined to form a neutral solution.
How can we find the acidic nature of the substance?
The [tex]\rm{H^{+\\} }[/tex] ion shows the acidic nature of the substance on the other hand pH value is also useful to further find the acidity of any substance. pH ranges between 0 to 7 show acidity.
