Answer:

The solution is 50 %wt

Explanation:

50% wt is a sort of concentration and means, that 50 g of solute (in this case, the potassium bromide) dissolved in 100 g of water.

It is the same to say, that there are 50g of KBr for every 100g of H₂O

Suppose there is 1. 00 l of an aqueous buffer containing 60. 0 mmol of acetic acid (pa=4. 76) and 40. 0 mmol of acetate. Calcula
8_murik_8 [283]

For 1. 00 l of an aqueous buffer containing 60. 0 mmol of acetic acid (pa=4. 76) and 40. 0 mmol of acetate, the pH of this buffer is 4.58.

<h3>What is handerson Hasselbalch equation? </h3>

It is expressed as:

pH = pKa + log [A-]/[HA]

where,

[A-] is the molar concentration of conjugate base

[HA] is the molar concentration of weak acid

Given,

pKa = 4.76

<h3>Calculation of concentration:</h3>
  • For acetic acid

C = n/V

= 60/1000

= 0.06M

  • For acetate

C = 40/1000

= 0.04M

Now, substituting values in equation we get,

pH = 4.76 + log(0.04/0.06)

pH = 4.76 + (-0.176)

pH = 4.58

Thus by using Henderson Hasselbalch equation we find the value of pH of the buffer is 4.58.
