Buffer solutions are defined as equilibrium 10) systems that resist changes in acidity and maintain a constant pH when acids or bases are added to them. A buffered solution generally consists of a weak acid and its conjugate base, or a weak base and its conjugate acid. Which of the following pairs would be acceptable as a buffer: a) CH;COOH/ NaCOOCH;; b) NaHCO;/ Na,CO;; c) H,SO,/ NaHSO,; d) NaOH/ H,O; e) NaHSO,/Na,S04. Explain vour answer for each nair

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
