Respuesta :
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.

Orange juice has lower pH, so it is more acidic.
The pH of the orange juice is 3.7.
What is pH?
pH is a quantitative measure of the acidity or basicity of aqueous or other liquid solutions.
The relation between hydroxide ion ([tex]OH^-[/tex]) and hydronium ion ([tex]H_3O^+[/tex]) is given by:
pH + pOH = 14, which is equivalent to [[tex]H_3O^+[/tex]] [[tex]OH^-[/tex]] = [tex]10^ -^1^4[/tex]
Grape juice
pOH = -log [1.4 x 10⁻¹⁰] ≈ 9.6
pH= 14 - pOH = 14 - 9.6 = 4.4
Orange juce
pH= -log [1.8 x10⁻⁴] = 3.7
Hence, orange juice has lower pH, so it is more acidic.
