What acid is stronger Pepsi or orange juice?

Answer 1

Pepsi: phosphoric acid has 3 pKa values: 2.14, 6.86 and 12.4

Orange: citric acid has 3 pKa values:3.13, 4.76 and 6.40

Since phosphoric acid has the lowest pKa (2.14), it is the stronges acid: Ka value is 10 times higher! ( inv.log10(3.13-2.14)= 10)

Answer 2

Orange Juice is more acidic than Pepsi. The acidity of a substance is typically measured by its pH level, with lower pH values indicating higher acidity. Orange juice usually has a pH of around 3.5, while Pepsi tends to have a pH of around 2.5, making Pepsi slightly less acidic than orange juice.
