Acid rain affects both the urban (destroy historically important structures) and natural environment (damages vegetation in forests and reduce pH of rivers and lakes)...
that what i thought too, this is my working out
= 0.1x2 (because its a diprotic) x 8/100
= 0.016
= -log[0.016]
pH = 1.8 (1.d.p)
but the answer is 2.1 so don't no what i'm doing wrong ><'
