Lemon juice is below 7 on the pH scale, typically around 2 to 3. This makes it acidic.
No. Lemon juice is acidic, so it will have a lower pH.
The pH value of the juice lemon is under 7.
7 seeds
The pH value of lemon juice is 2.about pH = 2 to 2.5
Generally a lemon has a length of 60-70 mm (6-7 cm).
Lemon water is still acidic, you can easily test this yourself with a basic pH meter (they don't cost much). As the lemon water becomes more dilute it will approach the pH of the water. Tap water is commonly slightly alkaline (pH 7.4 or so) and so at very high dilutions the lemon water will exceed 7, but then there really isn't much lemon in it by that stage. pH < 7 is acidic, pH > 7 is alkaline.
I am guessing it is 7 to 15 cm long
Vinegar, lemon juice, and coffee are all common materials with a pH less than 7.
The pH of pure water is 7 (neutral). Adding lemon juice (which is acidic) will decrease the pH, making the solution more acidic. Lemon juice typically has a pH of around 2, so the pH of the water will decrease to a value closer to 2 when lemon juice is added.
A lemon produces about 7/10 of a volt of electricity.
Lemonade has a pH of about 2 or 3. Acidic substances have pH's below 7 and while bases have pH's above 7. Pure water (deionized) has a pH of 7.0. (Tap water is generally slightly acidic with a pH of ~6.5).
