Question
Which may be added to one litre of water to act a buffer:
Options
A.One mole of CH3COOH and one mole of HCI
B.One mole of NH4OH and one mole of NaOH
C.One mole of NH4CI and one mole of HCI
D.One mole of CH3COOH and 0.5 mole of NaOH
Solution
HC2H3O2 + NaOH → C2H3O2Na + H2O
1 0.5 0 0
0.5 0 0.5 0.5
This solution contains weak acid + its salt with strong base. and thus acts as buffer.
