- pH - Wikipedia
In chemistry, pH ( piːˈheɪtʃ or piːˈeɪtʃ ; pee-AYCH) is a logarithmic scale used to specify the acidity or basicity of aqueous solutions Acidic solutions (solutions with higher concentrations of hydrogen (H+) cations) are measured to have lower pH values than basic or alkaline solutions
- What Is pH? - Definition, Uses, Facts - Science Notes and Projects
pH measures the concentration of hydrogen ions (H⁺) in a solution and indicates whether a solution is acidic, neutral, or basic The pH scale typically ranges from 0 to 14, where 7 is neutral, values below 7 are acidic, and values above 7 are basic (alkaline)

What is pH? Acidic and alkaine (or "basic") are two extremes that describe substances, usually liquids or chemicals, just like hot and cold are two extremes that describe temperature A substance that is neither acidic nor alkaline is neutral The pH scale measures how acidic or alkaline a substance is The scale ranges from 0 to 14
