Lemon juice lowers pH by increasing the amount of Hydronium ions and decreasing the amount of Hydroxide ions. pH is the measurement of Hydronium ions. If there is more hydronium ions, the lower the pH will be. Lemon juice increases the amount of Hydronium ions by adding a Hydrogen atom into solution when the citric acid dissociates.
The acids in lemon juice are much more active than any of the acids in cranberry juice resulting in lemon juice's lower freezing point.
I think they are both citric acid but lemon juice is more concentrated.
No. Lemon juice is acidic, so it will have a lower pH.
Lemon juice
To lower the pH of 100 ml of water to a pH of 5.5, it would take only around a drop of lemon juice. It is estimated that in a gallon aquarium, two drops of lemon juice can lower the pH by .5.
Lower pH indicates a dtronger acid. So the lemon juice would be stronger.
apparently it's anywhere between 3 tb to 1/4 cup
lemon juice
Lemon juice contains citric acid (among some other) that gives it an acidic pH value of about 2.0 or lower.
Lemon juice can inhibit some bacteria if they are sensitive to lower (acidic) pH. As lemon juice is an acid. But there are very high numbers of bacteria in lemon wedges when tested. See link below:
One single drop! Every single drop of lemon juice will lower the pH a tiny bit. You need to specify to what value you want to lower the pH
