Chemistry question dealing with concentration and pH please help?
1. pH = -lg(3.8 * 10^-9) = 8.42 since pH > 7, hence the solution is basic pOH = 14.0 - pH = 5.58 5.58 = -lg(conc. OH- ions) conc. OH- ions = 10^(-5.58) = 2.63 * 10^-6 2. pOH = -lg(1.6*10^-6) = 5.80 pH = 14.0 - pOH = 8.20 since pH > 7, solution is basic pH = -lg(conc. H3O+ ions)...- imported_Kyosuke
