2 log(4y) = log7(343) - log5(25)
log7(343) = 3
log5(25) = 2
2 log(4y) = 3 - 2 = 1
log(4y) = 0.5
4y = sqrt(10)
y = 0.25 sqrt(10)

Determine the pH of a 5 M HA solution at 25 degrees Ka 7.1 x 10-4?
Given that Ka = 7.1 x 10-4 pKa = -log[Ka] = 3.15 (2 s.f) pH = 1/2pka - 1/2log[A-] = 1/2(3.15) - 1/2log[5] = 1.575 - (-0.3495) pH = 1.93 (2 s.f.) So the pH of HA = 1.93
