pH scale and pH chart.
pH stands for potential of Hydrogen.
It is used to find the numeric value of the level of acidity or basicity of a substance.
It is the most common and trusted way to measure how acidic or basic a substance is.
The chemical properties of many solution enables them to be divided into three categories-acidic, basic or neutral solutions.
The pH scale is used to measure acidity and basicity (alkalinity).
Solutions with a pH less than 7 are acidic.
Solutions with a pH of 7 are neutral.
Solutions with a pH more than 7 are basic (alkaline).
The pH scale reads from value 0-14.
Solutions with pH less than 3 are strong acids.
Solutions with pH values of 3-6 are weak acids.
Solutions with a pH value of 7 are neutral.
Solutions with a pH value of more 8-11are weak bases.
Solutions with a pH value of 11-14 are strong bases
