Question

Egg yolks have a ph of 5.6; milk has a ph of 6.6; orange juice has a ph of 3.6; and water has a ph of 7. what is the difference in hydrogen ion concentration between milk and orange juice?

Answer 1

orange juice has a higher concentration of H+ ions. hydrogen ions give rise to the acidic properties hence a lower pH indicates a higher H+ ion concentration

Answer 2

pH=-lg[H⁺]

[H⁺]=10^(-pH)

[H⁺]m=10^(-6.6)

[H⁺]j=10^(-3.6)

[H⁺]j/[H⁺]m=10^(-3.6)/10^(-6.6)=1000

Hydrogenium ion concentration in orange juice is in 1000 times more, than in milk.
