pH

• pH generally from $0$(very acidic) to $14$ (very alkaline).
• pH should be thought of simply as a number that indicates the basic or acidic nature of a solution.
• The higher the hydronium ion concentration, the lower the pH value.
• The pH of a neutral solution is $7$.
• Values less than $7$ on the pH scale represent an acidic solution.
• Values greater than $7$ on the pH scale represent a basic solution.

the pH of lemon juice
