Calculating the expected pH of the buffer solution: Given that the pKa for Acetic Acid is 4.77, calculate the expected pH of the

ser-zykov [4K]

Answer:

$pH=4.77$

Explanation:

From the question we are told that:

pKa for Acetic Acid $pK_a= 4.77$

Therefore

For Equal Concentration of acetic acid and acetatic ion

$CH_3COOH=CH_3COO^-$

Generally the Henderson's equation for pH value is mathematically given by

$pH=pK_a+log\frac{base}{acid}$

$pH=4.77+log\frac{CH_3COO^-}{CH_3COOH}$

$pH=4.77+log1$

$pH=4.77$
