1) a solution with a hyrdrogen ion concentration of 1x10^-4 moles/liter would have a ph of what?
2) a solution with [h^+]=1x10^-12 moles/liter has a ph of what and is a what?
3) a solution with a ph of 6 would have a [h^+] of what?
explain answers.

pH = -log(concentration of hydro.gen ion)

1. When con. of H ion is 1*10-4 mol/L

pH = -log(1*10-4) = -(-4) = 4

2. A solution with a pH of 1*10-12mol/L

pH = -log (1*10-12) = -(-12) = 12

The pH is 12 and the solution is basic or alkaline

3.A solution with a pH of 6 has the concentration of

pH = -log (H+)

(H+) = arc log -pH

(H+) = 1*10-6

Explanation:

it is reliable if two scientists recorded it
