Step-by-step explanation:
it is bcs 913/4 and the same concept is used
The equation should look like :
[H+] = (1-a)(x) + (a)(y)
Where:
5.8 = -log [H+]
5.0 = -log x
6.9 = -log y
(1-a) = proportion of x
<span>a = proportion of y
so calculating a will give you the result of how many ounces are required</span>
It's the first one. y = 3x
proportional means they are just some multiple of the other.
