Keq: [SO3][NO] /[SO2]NO2]
Explanation:
Answer:
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
