Hydrogen ion concentration in mol/L in a solution of pH 5.4 will be
3.98 x 108
3.88 x 106
3.68 x 10-6
3.98 x 10-6
pH = −log[H+] 5.4 = −log[H+]; [H+] = 3.98 × 10−6
At 25∘C, the dissociation constant of a base BOH is 1.0 × 10−12. The
concentration of Hydroxyl ions in 0.01 M aqueous solution of the base
would be
0.1 mol of methyl amine (Kb = 5 × 10−4) is mixed with 0.08 mol of HCl and the solution is diluted to 1 litre. The hydrogen ion concentration of the resulting solution is:
