The pH of water collected in a stormwater run-off 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.
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 10x button. It should return 1.51 x 10-5
