Could you show full working for this question? Thanks.
Lemon juice with a [H+] of 1.6x10^-4 molL-1 was mixed with an equal volume of orange juice with a [H+] of 1.3x10^-6 molL-1 to make a citrus juice drink. Calculate the hydrogen and hydroxide ion concentration of the citrus drink.
Answer: [H+]= 8.07x10^-5 and [OH-]= 1.24x10^-10

This is a bad question, the [H+] would depend on the relative amounts of each solution.
Assuming it is 1:1, you could simply average the two solutions.
(0.00016+0.0000013)/2 = 0.0000807 = 8.07*10^-5
[H+]*[OH-] = 10^-14 for water.
So, [OH-] = 10^-14/(8.07*10^-5) = 1.24*10^-10
