The ratio of [sodium acetate] to [acetic acid] in a buffer solution is 0.30.

Henderson–Hasselbalch equation: pH = pKa + log(cs/ck)

pH = 4.25; pH of buffer solution

pKa = -log(1.7 × 10−5) = 4.77

4.25 = 4.77 + log(cs/ck)

log(cs/ck) =4.25 - 4.77 = -0.52

cs/ck = 10∧(-0.52) = 0.30; ratio of sodium acetate to acetic acid

A buffer can be defined as a substance that prevents the pH of a solution from changing by either releasing or absorbing H⁺ in a solution.

Buffer is a solution that can resist pH change upon the addition of an acidic or basic components and it is able to neutralize small amounts of added acid or base, pH of the solution is relatively stable.

natali 33 [55]

Answer:

If the concentration of product D is increased, the rate of the reverse reaction would increase.

Explanation:

Chemical reaction:

A + B ⇄ C + D

In given condition the equilibrium is disturb by increasing the concentration of product.

When the concentration of product D is increased the system will proceed in backward direction in order to regain the equilibrium. Because when the product concentration is high it means reaction is not on equilibrium state the reaction will proceed backward direction to regain the equilibrium state.

According to the Le- Chatelier principle,

At equilibrium state when stress is applied to the system, the system will behave in such a way to nullify the stress.

The equilibrium can be disturb,

By changing the concentration

By changing the volume

By changing the pressure

By changing the temperature
