What are 4 examples of buffer solution?
A solution of acetic acid and sodium acetate (CH3COOH + CH3COONa) is an example of a buffer that consists of a weak acid and its conjugate base, whereas a solution of ammonia and ammonium chloride (NH3 + NH4Cl) is an example of a buffer that consists of a weak base and its conjugate acid.What is buffer solution PDF?
Buffers are compounds or mixtures of compounds that, by their presence in solution, resist changes in pH upon the addition of small quantities of acid or alkali The resistance to a change in pH is known as buffer action.What are the types of buffer solutions?
There are two types of buffer solutions: acidic buffer and basic buffer: A solution with weak acid and its salts containing strong bases is called an acidic buffer solution. E.g., A solution with CH3COOH, which is weak acid and CH3COONa, which is its salt is an acidic buffer solution.- A buffer solution is defined as a solution which resists any change in its pH value even when small amounts of the acid or the base are added to it. e.g Ammonium acetate acts as a buffer.
