Which of the following mixtures, when dissolved in 1.0 L of water, would function as a buffer?
0.10 mol of sodium hydroxide (NaOH) and 0.10 mol of hydrochloric acid (HCl)
0.10 mol of ammonium chloride (NH4Cl) and 0.10 mol of ammonia (NH3)
0.10 mol of ammonium chloride (NH4Cl) and 0.10 mol of ammonium bromide (NH4Br)
0.10 mol of sodium chloride (NaCl) and 0.10 mol of ammonium chloride (NH4Cl)
more than one of the above would be suitable buffers
A buffer solution is a mixture of weak acid and its conjugate base or a mixture of weak base and its conjugate base. We can identify a buffer when there is difference of one H+ between weak acid and its conjugate base or when there is difference of one OH- between weak base and its conjugate base.
0.10 mol of ammonium chloride (NH4Cl) and 0.10 mol of ammonia (NH3) will acts as buffer.
