The mixed solution of pthallic acid and potassium hydrogen pthallate is _________.
a solution of a weak acid + salt of the weakacid and a strong base; is called an acidic buffer solution. Here Pthalic acid is weak acid and potassium hydrogen pthallate is salt of weak acid and strong base.
If $$0.00050$$ mol $$NaH{CO}_{3}$$ is added to $$1$$ litre of a buffered solution of $$pH\ 8$$, then how much material will exist in each of the three forms $${H}_{2}{CO}_{3},H{CO}_{3}^{-}$$ and $${CO}_{3}^{2-}$$? For $${H}_{2}{CO}_{3}$$, $${K}_{1}=5\times {10}^{-7}$$; $${K}_{2}=5\times {10}^{-13}$$
