A buffer solution in chemistry is a solution that resists changes in pH when an acid or base is added to it. It is a solution that contains a weak acid and its conjugate base (anion) or a weak base and its conjugate acid.

A buffer is able to resist a change in pH due to the conjugate base and conjugate acid of the weak acids and bases contained in them respectively. The conjugate base/acid are present in an equilibrium quantity with their acid/base counterparts and help to neutralize or react with any additional H+ or OH- from an acid or base added to their solution.

However, when a strong acid or base is added to the buffer solution, there is only a slight change which practically does not change the pH of the solution.

Hence, all of the above options about a buffered solution is true.

how The areas under the peaks on a gas chromatogram for a mixture of ethyl acetate and toluene were 85 "units" at 2.5 minutes el

nikitadnepr [17]

Answer:

74 % major, 26 % minor product

Explanation:

The total area under the peaks is

85 units + 30 units = 115 units

$\text{\% Major component} = \dfrac{\text{85 units}}{\text{115 units}} \times 100 \, \% = \mathbf{74 \, \%}\\\\\text{\% Minor component} = \dfrac{\text{30 units}}{\text{115 units}} \times 100 \, \% = \mathbf{26 \, \%}$
