Question

A sample of grape juice has a hydroxide ion concentration of 1.4 x 10^-10 M. Which of these equations will

you use to find the hydronium ion concentration?

Answer 1

Step-by-step explanation:

grape juice

pOH = -log[1.4*10⁻¹⁰]≈9.6

pH=14-pOH=14-9.6=4.4

orange juce

pH= -log[1.8*10⁻⁴]=3.7

Orange juice has lower pH, so it is more acidic.
