Question

Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH–] is 1 x 10–6 mol/L. Is this solution acidic, basic, or neutral? Show your work to receive full credit.

Answer 1

The hydrogen ion concentration (H+) for the aqueous solution in which (oh-) is 1 x10 ^-6 mol/l is calculated as below

we always know (H+)(OH-) = 1 x10 ^14

make the H+ the subject of the formula
H+ =1 x10^-14/ OH-

by substituting the OH-

H+= (1 x10^-14)/( 1 x10^-6)

H+ =1 x 10 ^-8 mol/l


the solution is basic since it contain OH- ions
