How does lemon kill bacteria?
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:
What happens to the pH when you add lemon juice to a soap solution?
When you add lemon juice, which is acidic, to a soap solution, the pH of the solution decreases. Soaps are typically alkaline, so the introduction of the acidic lemon juice neutralizes some of the alkalinity, resulting in a lower pH. This change in pH can affect the soap's ability to lather and clean effectively.
If you add lemon juice to pure water what would happen to the pH?
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.
While performing an experiment at home Emma adds lemon juice to a soap solution. How will this affect the pH of the soap solution?
When Emma adds lemon juice, which is acidic, to the soap solution, it will lower the pH of the solution. Soap is typically alkaline, so the introduction of the acidic lemon juice will neutralize some of the soap's basicity. As a result, the overall pH of the mixture will decrease, making it less alkaline and potentially more neutral or slightly acidic, depending on the amounts mixed.
Why does orange juice take a long time to evaporate?
Some compounds of the juice have lower vapor tension.
How much lemon juice would be needed to lower the pH of 100 ml of water to a pH of 5.5?
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.
Why would cranberry juice freeze before lemon juice?
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.
Is lemon juice or grapefruit juice more acidic?
I think they are both citric acid but lemon juice is more concentrated.
Would lemon juice have a pH close to 7?
No. Lemon juice is acidic, so it will have a lower pH.
What acid has a pH of 3 or lower?
Lemon juice
Lemon juice measurementhow much is the juice of one lemon?
apparently it's anywhere between 3 tb to 1/4 cup
What is the strongest acid lemon juice with a pH of 2.5 or tomato juice with a pH of 4.5?
Lemon juice with a pH of 2.5 is a stronger acid compared to tomato juice with a pH of 4.5. pH is a measure of the concentration of hydrogen ions in a solution, and the lower the pH value, the higher the acidity of the substance. Therefore, lemon juice would be considered a stronger acid in this scenario.
Is lemon juice an acid or akali?
Lemon juice contains citric acid (among some other) that gives it an acidic pH value of about 2.0 or lower.
How much does lemon juice lower pH?
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.
What cleans a penny better lemon juice or sprite?
Lemon juice is more effective at cleaning a penny compared to Sprite due to its acidic nature. The citric acid in lemon juice helps to break down the tarnish on the penny, restoring its shine. On the other hand, Sprite may not be as effective due to lower acidity levels.
Is lemon juise an acid an alkali or neutral?
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
Which would raise pH more ammonia vinegar coffee or lemon juice?
Ammonia, which is basic, would raise pH. Vinegar, coffee and lemon juice are all acidic and would cause pH to be lower.
