Fruit juices are acidic - pH under 7.
Lemon and juice are acids, so they would be on the higher end of the pH scale.
Salsa is less acid than lemon, so pH is higher.
Lemon juice. It has a pH of 2.3, whereas orange juice has a pH of 3.3. What is being cleaned off is the CuO and CuCO3 that forms on the penny. Both O2- and CO32- are bases, so the stronger the acid, the more effectively they will be reacted away. I did a quick online search for the pH of grape juice but did not find anything, but given that it lacks the sour taste that orange and lemon juice have (an indicator of acidity), I would have to assume that it is not as acidic as either lemon or orange juice.
The pH value of lemon juice is 2.about pH = 2 to 2.5
The pH value of the juice lemon is under 7.
Lemon juice has a pH of around 2.3 which is acidic because the juice in the lemon is very acidic.
The pH of orange juice after a week is pH 5.
No. Lemon juice is acidic, so it will have a lower pH.
Vinegar has a pH range of about 2.4 - 3.4. Apple juice: 2.9 - 3.3 Grapefruit juice: 3 - 3.3 Lemon juice: 2.3 Orange juice: 3 - 4
Lemon juice has more acid because of its density and it contains more sodium.
The pH level of orange juice is 3.3
