The pH of water collected in a stormwater runoff downstream from a Union Carbide chemical factory is 4.82. Calculate the H+ ion concentration of rainwater.
The problem may start with:
pH= log H+ = 4.82. The answer is 1.5x10 power 5. Again, Can you please show steps for maths.

DrBob222,
pH =log(H^+)
4.82 = log(H^+)
log(H^+) = 4.82
Take the antilog of both sides.
The antilog of log (H^+) is, or course, just (H^+). To find the antilog of 4.82, punch that number into your calculator and hit the 10^{x} button. It should return 1.51 x 10^{5}
