Grape Juice typically has a pH between 2 and 3. Grape juice with a pH of 1 is unusually acidic, and can be considered dangerous.
This juice has a pH under 7 because contain citric acid.
Not usually unless the pH is less than 1. Mild acidity in a solution is usually harmless. Lemon juice has a pH of about 2, but lemons usually aren't considered dangerous.
A pH indicator can be made out of grape juice or beetroot or even eggplant. Grate 1/4 cup of beetroot or eggplant into 2 cup water, boil for 10 min and strain for the dark liquid, by the way grape juice could be used right out of carton. Add indicator to the substance that is being tested, it will be more red for pH of 2 and greener for pH of 12, and test for better knowledge of all colors that pH indicator can turn.
pH of stomach juice is between 1 and 2.
Between the pH of 1-4.
The ratio is 1:1 000 000.
1-Battery Acid, 2-Lemon Juice, 3-Vinegar, 4-Acid Rain
The pH of lemon juice is normally around 2-3 pH. It is defintely a strong acid. Stomach acid is 1 on the pH scale. It isn't neutral, definetly NOT a alkali. Hope this helps. Lolly x
Some acids are not dangerous because they aren't strong acids. The strength of an acid/base is measured on the pH scale. The closer to 7 the weaker. Under 7, is an acid and above 7 is a base. If something has a pH of 1 then it is a dangerous acid, while acid with a pH of 6.5 are not dangerous for example.
The pH of vinegar is around 3.4. The pH of lemon juice is around 2.3. Since pH = -log(conc. H+ ions), we simply need to solve for the conc. of H+ ions in both substances and find the difference. There are approximately 4.6 x 10^-3 M hydronium ions in lemon juice than vinegar.
'Stronger' , I think you mean higher or lower. A Car Battery contains sulphuric acid . Hence pH = 1 Lemon juice is an acid in ots own right ; Hence pH = 4 The lower the pH value to more acidic (Not Stronger) it is.
Yes it is. The pH of water is neutral or 7, and lemon juice is a very low 1 or 2. With the water, the resulting pH is more neutral and less acidic than lemon juice alone.
