1.) Calculate the concentrations of all species present (Na+, C6H5CO2-, C6H5CO2H, H3O+ and OH-) in 0.060M of Sodium benzoate. The pH is 8.48 and Ka = 6.5 x 10-5.
2.) Calculate the concentrations of H2SO3, HSO3-, SO32-, H3O+ and OH- in a 0.025M H2SO3. The pH is 1.88 and the Ka1= 1.5 x 10-2 and Ka2 = 6.3 x 10-8.
A buffer solution of pH of 9.25 contains P mol of a weak base and Q mol of a salt of its conjugate acid. When 120 cm3 of a 0.0140 mol.dm-3 solution of hydrochloric acid was added to this buffer solution
To an open beaker containing 500ml of water at 298k, 20g of sodium metal is added. the reaction proceeds quite rigorously but ultimately comes to rest after consuming all of the sodium metal and thermally reequilibrating with the surroundings. The..
