PH can be calculated using the following equation
pH = -log [H₃O⁺]
for apple juice the hydronium /hydrogen ion concentration is 0.0003
pH = -log (0.0003)
pH = 3.5
correct answer is C
For ammonia
pH = -log (3.1 x 10⁻⁹)
pH = 8.5
answer should be 8.5
(2x²/3)=dg
2x²=3dg
x²=((3dg)/2)
So x=√((3dg)/2) or x=-√((3dg)/2)
3.5 + 3.5 +9+9 = 25. ;) i gotchu again.
