Lemon and juice are acids, so they would be on the higher end of the pH scale.
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
A lemon produces about 7/10 of a volt of electricity.
no. pH is a rating of how alkaline or acidic a liquid is. 7 is neutral. lower than 7 is acidic. higher is alkaline. lemon juice is acidic. so the rating would go down.
Citric acid and water is the main componenst of lemon juice as water is neutral and Citric acid is an acid it has a pH <7
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).
