What has the highest pH value dilute sodium bicarbonate or lemon juice hydroxide solution?

The correct answer is: dilute sodium bicarbonate.

The pH value is a measure of the acidity or basicity of a solution. The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 are acidic, while values above 7 are basic. The higher the pH value, the more basic the solution.

Dilute sodium bicarbonate is a basic solution, with a pH value of around 8.3. Lemon juice is an acidic solution, with a pH value of around 2. Therefore, dilute sodium bicarbonate has a higher pH value than lemon juice.
