How many times more acidic is acid rain with a pH of 2.4 than an ordinary rain with pH of 6?

Question

.sam. · Answer

Moving from pH of 6 to 5 is about 10 times stronger.

anonymous · Answer

May I ask what formula did you use, if you used any at all?

.sam. · Answer

-log[H+]=pH

anonymous · Answer

thats odd my textbook says the formula is [H+]=10^pH

anonymous · Answer

*-pH

.sam. · Answer

its the same, you take the log of both sides

.sam. · Answer

-log[H+]=log10^pH
-log[H+]=pHlog10
-log[H+]=pH

anonymous · Answer

so if pH is 2.4....damn hold on a sec...

anonymous · Answer

oh i see, so its (10^-2.4/10^6)=10^4.6?

.sam. · Answer

yes

anonymous · Answer

and I can just state it was ten times stronger, not 10,000?

.sam. · Answer

no don't say 10,000 times stronger that will be inaccurate

anonymous · Answer

alright I'll stick with 10 times stronger thank you so much I have a final and I'm trying to study hard right now. Have a good night.

.sam. · Answer

NOOO, don't use 10 times! that's just a definition,

The answer is 
-log(3.98x10^-3)=2.4
-log(1x10^-6)=6

Divide both concentrations,

3.98x10^-3 / 1x10^-6 

You will get 3980 time stronger
