Natural rainwater (pH 5 - 6) Milk (pH 6 - 6.6)
an acid. one example of a pH 6 substance is urine.
There's no such thing as a base of an acid! A base is a substance with a pH of 8-14, and an acid is a base with a pH of 0-6. A neutral substance has a pH of 7.
If a substance has a PH of 11 then the substance is basic.
a weak acid
Acids.
pH is the power of 10, so 6-2=4 means 104 times stronger (10.000 times)
The pH scale ranges from 0-14. From 0-6, the substance is acidic. A value of 7 means the substance is neutral. From 8-14, the substance is basic.
The pH is the negative log of the concentration of hydronium ions. (pH=-log [H3O+]) If the pH is high, the substance is basic. If it is low the substance is acidic. When the pH is exactly 7 the substance is neutral.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
Strong acids have pH values below 3 , so it is a weak acid.
